Ok, I recently re-did my calipers using oven cleaner and baking them(I rebuilt them afterwards) and figured using a metal brush to get the crap off would be enough to promote the paint to stick to the surface. Well yesterday I dropped one on accident and some paint chipped off, should the paint be bonded better than this? anyone have any tips for putting a second layer on them? should I wetsand them first?

 

What kind of paint is it? Anything in a rattle can form the auto parts store is going to be crap...

 

its duplicolor brake caliper paint

 

I've never had problems with adhesion with that paint. Sure it starts to chip after a year or two, but if you didn't want it to do that you should have powder coated them.

 

^x2 i did mine on my old winter car and they held up for 3 years now. i used brake cleaner and painted them
