Over the years my car's bumper has took a bit of punishment, and now I'm left with a couple of gouges that need to be sorted out.
My car's colour is flat red, and the bumpers are painted.
So ive bought some wet and dry of varying thicknesses and some plastic bumper filler. It seems pretty easy - clean the area, put the filler in, wait for it to dry and then sand it down so you have a smooth surface.
This is where my question starts - whats the best technique for getting as good a finish as possible? Do I need primer (as its a plastic surface i'm painting). How many coats should I put on? Do I need to sand down the paint in between coats?
So yeah, any advice on how to do this would be great, or links to places where I can get good info.
