Driving a car means picking up some bumps and bruises along the way. Minor paint damage isn't the end of the world and touching it up is just part of its regular upkeep, much like changing a worn-out part. These imperfections not only sully your vehicle's appearance, but left unattended, can also lead to deterioration below the surface, including rust.
Fortunately, with the right tools and a bit of patience, touching up your car's paint is a task most DIYers can undertake with relative ease. Here's five tips to help you take on the task.
Sometimes all it takes is a good polish to remove superficial blemishes. Unless the damage has clearly exposed primer or bare metal, it's advisable to first attempt polishing out imperfections with a polishing compound and then working up to a rubbing compound, if needed. This less invasive method preserves the vehicle’s original finish and is simpler and more cost-effective.
The fingernail test is a good rule of thumb: if your fingernail doesn’t catch in it, the scratch is probably shallow enough to be polished out without applying new paint. If polishing doesn't work, you’ll need to apply touch-up paint.
Manufacturers assign a unique paint code to each original factory color. This code is typically found on a sticker or plate inside the vehicle, such as on the driver's side door jamb, under the hood or in the trunk. With the code, you can confidently order touch-up paint from an auto parts store, dealership or online outlet, knowing it’ll be a precise match.
A successful touch-up job starts with careful preparation. First, clean the area thoroughly with a mild detergent or car wash, rinse thoroughly and clay bar the surface to remove all dirt, grime or debris.
Next, dry everything completely with a soft microfiber towel to prevent moisture-related issues like peeling or bubbling. Then carefully and completely cover the surrounding areas with masking tape and lightly sand the affected area with very fine sandpaper to remove any rough edges or rust.
Now for the fun part: filling in the scratch. If there's exposed metal, begin by applying a thin layer of primer, allowing it to dry as per the manufacturer’s instructions. This provides a protective base for the paint to adhere to.
Next, apply the touch-up paint. The choice of application tool depends on the size of the damage. A paint pen or small brush works well for minor scratches and chips, while a spray can is better for larger areas. If you’re using spray paint, make sure you wear a face covering and your workspace is well ventilated.
Apply the paint in thin, even layers, letting each layer dry thoroughly before applying the next. This gradual build-up helps achieve a smooth, level finish. After the paint has dried, apply a clear coat layer over it to seal and protect the new finish and match the rest of the car.
Though touch-up work may look showroom-ready, it's not time to hit the local Cars & Coffee gathering just yet.
First, allow the paint and clear coat time to cure completely. Depending on the products used and environmental conditions, this usually means waiting at least 24 to 48 hours.
Once the touched-up area is fully cured, consider a final polish. This enhances the depth and luster of the finish, helping it blend seamlessly with the surrounding area. Use a fine polishing compound with a soft cloth. Be gentle to avoid damaging the new surface.
Follow this with a thorough car wash to remove any residual polishing compound or dust. Finally, you also can apply a layer of wax to add an extra protective layer.
Take Your Time
A project like this will not only save you a potentially expensive trip to the auto body shop it will instill a sense of pride in maintaining your car's appearance. Just remember that the key to a successful touch-up paint job is patience and attention to detail at every step. It’s an easy way to keep your car looking great for the long haul.
