I blasted my frame with Black Blast from Menards, no silica dust to inhale or get embedded into frame and works very well. Left the frame with a lot of sharp "tooth" and grit to adhere to. Blew off the frame with filtered compressed air and coated with POR. I did not acid etch. POR went on great and I cant even scatch it. So far no adhesion or peeling with assembly of the truck. Did not top coat either but wish I would have while tacky just for extra insurance. Time will tell...
