primer
 

After I have my super shot blasted what is the best primer to use to keep the rust away and what is the best gun to spray with, suction or gravity fed??

Well from what I have read and gotten from classes is that the best gun for priming would be a gravity feed. Good steady flow and less parts for it move through. As for the primer itself Im still working on that.

Find out what company you will use for "top coats" first. Then choose primer from that company for best results. Some companys have a two part "epoxy primer" that is shot on bare metal, and other's have to use a "etching primer" before shooting a "sandable" primer. ALL COMPANYS highly reccomend a "sealer" after primers to seal of any bleed through of fillers, or OEM paint left on car that was still in good shape. Yes, gravity feed is the way to go for spraying. (HVLP gun is best)
