I have some pealing clear coat on my hood, do you think doing this would be a good approach too instead of having the whole thing resprayed?
A vehicle needs to be repainted when the clear coat has failed. Otherwise a professional retailer can restore the paint in most cases. If the paint has severe oxidation, use a paint cleanser or polish to remove a section of the oxidation and then look closely for crow's feet (little deep scratches that go in multiple directions).
Having your car repainted is an investment in many ways. If the car isn't in good condition otherwise, repainting it may turn out to be more expensive than the car is worth on resale. Some insurance policies cover the cost of bodywork if the vehicle was damaged in an accident.
There is no such thing as a really smooth paint application out of a gun. Yes, if done properly it can be pretty nice, but there will always be some orange peel effect. Polishing removes a tiny amount of the top layer of finish, leaving a glass flat surface. This must be done very carefully as it is easy to take off too much, especially at edges and peaks.
To fix a peeling clear coat on your car, start by scrubbing the peeling area with 1000-grit sandpaper to get rid of the damaged coat. Then, soak 2000-grit sandpaper in water for an hour before sanding around the damage to blend the repair area with the clear coat. Let it dry for 5 minutes, then spray on a second coat.
If the existing finish is still relatively new and in good shape, and you just want to change the color or put something like a pearl coat over it (as we show later), then sanding down the existing paint and recovering it should be fine. ... If so, it can be painted over like the rest of the car.
