so i want to repaint my entire truck. only problem is it has some DEEP scratches(down to bare metal) what is the best way to paint it? do i have to strip all the paint to bare metal then prime it? or do i just prime over the current paint? i am doing this on a $600 truck, so i really dont care if i #### up - its my first time - i just want to learn how to do it. i will be getting a compressor and spray gun - will this be enough for a professional job? or do i need chemicals to take all the current paint off? any help would be greatly appreciated
