Re: cbr900rr Painting Frame, prep ?
Must sand w/ 320. Then use a eching primer. If you don't prep correctly the paint WILL peel. Alum is soo smooth and the pores are not deep.
Go to you local auto paint supply shop and talk to a paint jobber. Every paint has it's own process. Meaning you can't use certain primers with some bases and top coats. Tell your jobber what it is you are trying to do and they will steer you the right way.
Single stage paint?
Two stage paint?
These are all things you will need to think about BEFORE you buy the paint.
Auto paint is really $$$$$$$$ make sure you get what you want.
