Step 1: Bear on Up Kits

Duplicolor has unproblematic pigment bear upon-up kits that y'all tin buy at your local motorcar parts store, and many dealerships can sell you lot a paint pen in your automobile'southward exact factory color. You tin can also purchase more than involved touch-upward kits and supplies online. For example, the kit we tested from PaintScratch came with primer, clearcoat, paint thinner, a bottle of rubbing chemical compound, and color-matched paint.

PaintScratch used information in the car's Vehicle Identification Number—the long combo of messages and numbers commonly referred to every bit a VIN—to verify the right shade of paint, which is a pretty mutual practice. These kits are more expensive and have more steps, but ultimately provide a amend, longer lasting upshot.

Step 2: Check the Door

You need to identify the pigment code for your vehicle to ensure yous are getting the correct shade of pigment, which is easy to notice if your car has never been repainted a different color. On most cars built since 1983, this data may be found on a sticker on your commuter'southward door or door jamb. To exist absolutely sure of a lucifer, the paint vendor may besides need the VIN, which can be found on that same door sticker or on the VIN plate on your dash.

If your motorcar has been repainted a unlike color in its lifetime, you'll obviously need to discover that colour instead. Hopefully that color is listed somewhere in the records for the automobile, simply if not, you'll probable want to shop for pigment in person to make sure you're getting a good lucifer.

Footstep three: Go Shopping

Preparation is the key to getting good results. You'll need very fine 1000-grit, 3M Wetordry sandpaper, various craft sticks, cotton wool swabs, sparse-tip splinter tweezers, mucilage dots, and various paper punches. Everything except the tweezers came from a local craft store.

Stride 4: Making Your Sanders

Virtually off-the-shelf sanding tools would harm a lot of perfectly fine paint around the fleck, and then we'll demand to make our own miniature sanders. Utilize the punches to cut out small sandpaper circles and glue them to the craft sticks and dowels. Don't be agape to think outside the box at the craft store, either. We constitute a $1.99 pocketbook of wooden axles with dainty rounded ends that worked well on larger fries.

Step 5: Wash the Car

Get-go, launder the car with warm soapy water, rinse thoroughly, and let it dry. Y'all want to be sure the auto is completely free of dirt in gild to get a shine repair.

Stride 6: Remove Built Upwardly Waxes and Coatings

Next, remove any wax, grease, and silicone that would prevent fresh paint from adhering to the surface of your car. PPG Acryli-Make clean is one such solvent that'due south safe for this, and can be found at professional body shop stores and some larger auto parts stores.

Step 7: Make full Small Chips

For very small chips, we recommend using a paint pen. The small tip on the Duplicolor pigment pen was piece of cake to control and made filling the divot easy. Apply enough pigment that it rises barely above the surface. This allows for shrinkage during drying, and any slight excess can be wet sanded down and so rubbed smooth.

Almost stone fries are probably on your hood's leading border. To prevent the paint from running before it dries, you can lift the hood until the chip is horizontal to the ground to keep the paint in its place even while wet.

If these are the only chips your car has, you lot're lucky! Otherwise, read on.

Pace eight: Clean Up Medium Fries

If your remaining fries are larger, skip ahead to Pace 11. For medium size chips, we'll need to use the brush applicator. Before your first brushing on anything, make clean out any loose debris and paint from inside the bit with your tweezers.

Step 9: Apply the Primer

Use the primer with the applicator castor as directed. It's important to read and follow the instructions, every bit these tin vary betwixt pigment vendors. Pay close attending to how long it will have for the paint to dry for each layer, exist it primer, paint, or clearcoat. Working over wet pigment could leave rough spots, bubbling or holes in the finish, which wouldn't do as much to protect or heighten the appearance of your car.

Step ten: Apply the Paint

After the primer cures, apply the pigment. At this point, the filled fleck on our test car didn't wait too bad from six feet away. Wet sanding, applying the clearcoat, wet sanding again, so rubbing the chip polish improved the look of the repair considerably. After that, the repair looked great from about 3 feet abroad, depending on your eyesight and the amount of sunlight. You'll take to decide how much work you desire to invest here.

Pace 11: Make clean Upward Large Chips

The rest of these steps are for fixing big paint fries, which are the ones most probable to expose the car'southward blank metallic to the elements and pb to farther impairment. On larger fries and those that already have a rust colony growing, employ the splinter tweezers or a fine dental selection to flake off whatsoever loose paint.

You must exist very careful because you can easily plough a small scrap into a big one if yous loosen up whatsoever paint that isn't loose already. Still, if you don't remove the loose paint, the pigment will somewhen scrap off on its own and spoil the repair.

Step 12: Remove Rust

Swab CLR, Ultra 1's Safest Rust Remover, or an equivalent rust remover into the scrap to dissolve and remove rust. Continue doing this until your swab comes upward make clean. Next, rinse the rust remover out of the chip with isopropyl booze. If you lot don't remove all the rust, the pigment won't properly adhere to the car and rust will spread under the paint.

Step thirteen: Sand the Edges

Carefully dry-sand the edges of the flake until they look smoother and more rounded off. Y'all don't want any abrupt edges that volition make the repair wait more obvious. The curved shape of the wooden axle end fabricated it the ideal tool for this. Water volition restart the rust process, so do this sanding dry. The 3M Wetordry sandpaper clogs apace when used for dry sanding, merely the agglutinative dots make changing sanding circles easy.

Step 14: Utilize Leverage

Now is the time to whip out a flat craft stick to use with a small-scale circle of sandpaper. Using the edge of the flat wood sanding stick will apply more leverage when sanding the fleck and the area effectually information technology, simply don't sand too far outward or yous'll sand through the clearcoat and make the spot more noticeable.

You want to taper the edges of the flake so the boundaries of your repair are less noticeable. Make certain you lot wipe or blow off the remnants of your sanding job before moving on to the side by side steps.

Footstep 15: Apply the Primer

Advisedly apply the primer from the middle outward. You don't want to go across the border of the chip. If yous do, utilize a cotton swab moistened with lacquer thinner to quickly wipe up the excess primer. Keep all of your painting supplies close at manus on a pocket-size tabular array. You don't desire to accept to become searching and fumbling afterward a mistake as the paint doesn't stay liquid for long.

Step 16: Allow the Primer Dry

Allow the primer dry to full cure, which could accept a while depending on temperature and humidity. Be sure to follow the directions that came with your paint or repair kit, every bit they tin can advise you on the number of coats you lot'll demand for primer, pigment, and clearcoat too as the amount of time each layer needs to dry. Upkeep plenty time to let the primer completely dry out before covering it with pigment.

Step 17: Moisture Sanding

Once the primer dries, you lot can moisture sand information technology to gear up the primer base for pigment. In one case again, don't sand too far from the center of the chip or y'all will sand through the surrounding clearcoat. Sanding through the clearcoat is peculiarly noticeable if your car has dark or metallic pigment.

We recommend using a stronger, water resistant adhesive for these wet sanding sticks. Information technology'south non- removable, but y'all won't need to change sandpaper as often when moisture sanding. We pre-fabricated iii sticks with sand paper circles on each end for a total of 6 wet sanders.

Step 18: Steady Hands

Painting a flake this large with a castor will never requite you a factory terminate, but you can at least seal the metal back upward and go far look nice from farther away. Steady hands and a small amount of paint on the brush worked best. Take information technology from your local manicurist: Thin, polish coats are best when working with multiple layers.

Double- and triple-check that your primer is dry before you lot beginning this. While testing the PaintScratch kit, we made the error of painting too soon afterwards a second coat of primer. The solvent in the paint began to dissolve the primer and sparse swirls of gray mixed into the white.

Step nineteen: Add together Clearcoat

Keep wet sanding the painted spot until it is smoothen. Next, brush on the supplied clearcoat. Like the paint, clearcoat is lacquer based, thin, and it dries fast.

In this picture, yous can meet the boundary between the new lacquer and the original enamel. That happens when the edges of your repair aren't sanded down enough to taper into the chip. Be careful with your preparation work, and get the scrap as polish equally possible earlier you move on to the next pace. If you're happy with how your repair looks, though, you can skip ahead to Step 21.

Footstep 20: Repair Your Repairs

If your repair didn't turn out well the kickoff time, don't fret—at that place are ways to salvage it. After your previous try dries, sand the spot dorsum down to the primer with a 360-grit 3M Wetordry sandpaper. This time, information technology's imperative to stay within the repair zone, so you probably want to trim your sandpaper circumvolve to sit even with the radius of your stick. Wipe off any actress dust or moisture, then repaint the spot. Moisture sand the spot with thou-grit sandpaper once the paint is completely dry. Add together your clearcoat, then wet sand again. This tedious procedure slowly congenital up new layers of paint to sit fifty-fifty with the original surface.

Step 21: Use Rubbing Compound

In one case the repair is affluent with the residue of the paint, have some rubbing compound and polish the area with a clean cotton cloth. Launder the area with soapy h2o to clean off all the rubbing chemical compound, rinse thoroughly, and let it dry. Let the repair continue to cure for almost a week before waxing your car.

Step 22: All Done

All done! Hither is the same area where the large chip was, without whatsoever photoshopping. It won't fool a concours approximate, just it is a big improvement.

Of the products nosotros tested, the Duplicolor paint pen was the easiest to use on pocket-sized chips. The colour didn't match too equally the VIN-matched paint merely it was a deal at around $10. The $75.65 kit from PaintScratch was better for larger chips but required a tremendous corporeality of sweat disinterestedness and extra materials, plus the learning curve was steep. It cost Paul about $150 in materials and virtually 20 hours of work to get his paint chips fixed at abode, compared to a quote of most $300 to have his hood repainted.

Unless time is of the essence, elementary paint fleck repair is an easy enough task to attempt yourself. Accept care of chips as soon as y'all can! You're non simply saving money on a total repaint, but on future repairs. Your pigment is your auto's first line of defence force from the elements, later all. Treat it equally such.
