Painting an Alu frame

parryman

Going to cobble a hardcore hardtail out of the parts bin and was thinking of giving the frame a camo paint job.
Do I need to strip the old paint off completely, or will a scrub and scuff be enough to get the new paint to stick?

If I need to remove it all, any advice? Nitromoors and a wire brush?

The Rookie

If you can just use a course enough paper to give a key to the surface, that will work fine, stripping paint can either be easy or a real PITA depending on the original paint.

Nitromors is OK, but has been somewhat emasculated by the latest regulations, sometimes its cheaper to take it to a pro stripper.
