Hey mate!
im re-painting my bmx at the min so im kinda new to this aswell!
Basically you need sandpaper to rough up the old paint and take the gloss off!
Some Primer to be a base layer for the paint to stick on to and your spray paint and then..... (optional) sum gloss to put on top, you dont have to put this on tho! But it can reduce chips on the paint!
thanks
and take it to a car garage and ask them to spray it for ya if you dont wana do it your self!
p.s if anyone no if i can get sum cheap spray paint anywhere let me no! thanks
