with water based paint, you have to put a clear coat over the top, if you chip the clear coat and water gets behind it, it can cause the base coat to fade as the pigment is seperated from the panel. it happens rarely, but when it does it is a pain to put right! you can paint water based at home but it is very very very very very hard as you have got to keep the temp the same and fully dry the base coat before the clear coat, naturaly drying water based could take a while, in that time the panel could get covered in dust and the paint job ruined.
