So im going to media blasting a couple vehicles under neath I said and out engine bays all. I’m going to clean and degrease before blasting using a media to obtain an 80 grit tooth. Then apply epoxy. The cleaning stages is where I can’t decide. I’ve seen everything to just blowoff and spray epoxy. To spray wax and grease remover on and just blow off which would just float contaminatesI would think. To wash with dawn and water. Which I like this idea but I don’t want to prime over any flash rust. To go back over your blasted panels with 80 on a da and then grease and wax remover like normal but that seems like a lot of extra work when the tooth is already there. And you’d have to get all the nooks and crannies? Thanks for any input it’s greatly appreciated
