I had trouble with soft primers too .. Can you see what layer its seperating at ? Then figure out why .. Thats a very frustrating place to be .. I wouldn't paint 50 of something while at the stage .. Maybe do that cross hatch test (never did it myself).. Do your paint layers on a board ,,how ever you do it .. sealer,primer,paint,rattlecan?,waterbase?,protecti ve coat , epoxy or final coat .. Let dry .. Take a exacto knife and cut thru your finish criss,cross 1/4" squares,, Take a piece of duct tape and stick it down over that .. Now rip it off like a bandaid ,.. Where did it seperate ? There's your problem .. If nothing comes up you win .. ofcourse epoxy can can fail later in the water and negate all of the above .. At least then you know its your epoxy and where you stand ..

You know, the paint peeled right off the bottom of the plug but not the top. I did read in a recent post you shouldn't combine gloss and semi gloss paint. I did the top of the plug in gloss yellow, did the bottom in semi gloss white...stuff on the bottom half of the plug peeled off, including the primer, and the yellow is fine. Maybe combining gloss and semi gloss was the problem?
I only did one plug just in case there were issues...damage control is very important to me...
