I get good advice from you guy's on this site, thank you. g2 is all i have to work with, so i thined it about 3 to 1 and shoot it at about 80 lbs under the hood. i've been sanding for days with 400 dry, but i'ts not as bad as as shooting it stright with 45 lbs. still time consuming, i plan on covering showing metal with eatch primer in a can 3m and applying bc\cc
