Similarly, it is asked, can you use brake cleaner to prep for paint?

Re: Prep metal for paint I've used spray-on products like PRE from Eastwood, and have also used non-chlorinated brake cleaner. They clean the oily off, and evaporate quickly without leaving a residue. You can also use wax and grease remover in a spray bottle, but it needs to be wiped off.

Use 320-grit sandpaper over all filled areas to flatten and feather them out. Dust off the sanded areas with an old paint brush, and vacuum with a brush attachment. Finish by wiping down the wood with a damp cloth if using water-based paint or a tack cloth if using oil-based paint.

Do you need to prime bare wood before painting?

With the loose rust gone, your metal may either show extensive surface rust or little to no rust.

A primer specific to your amount of rust will help aid adhesion.
