It said you could use their acid metal prep before hand but then wash it off. I thought this was not the best idea. Where does it go and how do you control the resedue. If you wash it off won't it rust up then? Next it said to either sand or sandblast. I decided to blast.
Supose to be tenatious stuff. It actually cures from moisture so if moisture is present it sucks it out. It actually says best put on dry and cured in a damp environment. What are we the weathermen?
Can be primed, painted and should be topcoated as it will fade in UV. I thought I would use it for non-body parts; especially underbelly and areas hard to get to. That way if I did not get it 100% blasted I still have some protection.
