Summary hood rust autobody repair guide for the Do-It-Yourselfer

Even the smallest paint chip on the hood of your car can lead to some major problems in the future if you don’t take the time to fix it. Fortunately, there is a way to repair rust causing rock chips to prevent them from turning into a major issue. Below you’ll find a brief guide telling you how to perform repairs on small rock chips on the hood of your car. This solution is inexpensive, and will save you a lot of future hassle. Remember, this advice is for recent chips and is designed to prevent rust from occurring. If rust has already begun to form in the chip, you may have to spend a little more time fixing the problem.

Clean the Chip

Whether the chip was caused by flying debris out of the back of a gravel truck landing on your hood, or rocks getting kicked up off a road surface, the damage can be repaired in a similar fashion. First, you need to clean the chip of any paint that has been peeled or scratched from the surface. You can do this by taking a soft cotton cloth and using it to rub automotive polish around the affected area until there are no loose paint chips. Make sure not to rub too hard, as this can strip away the autobody’s protective clear coat as well as the damaged paint.

Reapply Primer and Paint

Once the old paint chips are cleared away, and you are left with a smooth spot to work on, you can prep the area to be primed and painted. First you will need to rub some denatured alcohol on the surface to get it completely clean and dry. This will ensure your new paint and primer go on smooth and won’t bubble after being applied. Once the surface is totally clean and dried, you can start to apply your primer. Take the butt end of a paper match and use it to cover the spot with a drop of primer. You will need to give it at least an hour to properly dry, depending on the surrounding climate, it may take 24 hours.

Once the primer has dried, you can apply the new car paint, after sanding if needed. You can usually find the right paint at a local automotive store. Car paints are typically sorted by year, make and model. Once you find a colour that you think matches, apply it to a piece of paper or cardboard to compare it to the existing car colour before you brush it on to the primed surface. If everything matches, you can gently apply the paint, and then let it cure for a few days. After it has cured, you can apply clearcoat and let that dry another few days before polishing. The difficulty is fitting these 3 layers into the little rockchip groove. You are bound to end up with a slight bump above the paint’s surface, but at least it won’t rust and spread across the hood. Applying thin layers to begin with, may help the end result.

If repairing the rust chips on your hood is unrealistic or if the rust has already started to spread, conveniently buy a aftermarket hood online at Canadian Part Source.
