i started removing paint with nasty paint remover, worked but several coatings,i have a heat gun i used fot inside varnish, but was really slow, the heat would blister paint,, then i would scrape . i started thinking about my small hand held torch,, well it worked great, i could remove white paint without going through primer although i will sand primer off and start afresh, . one thing that really was nice is as i was heating the paint once in awile a small black spot would show up ,, as i scraped away if there was any damaged wood , water penetration,, because of the fibers being weak .. it would flare up and the primer in that area would be marginal and discinigrate ,, not any bad depth to it but i wouldnt have seen the decay starting if the primer was still intact as with stripper ,, i would scrape around darkened area ,,usually about an inch, and sollid non effected wood would show up ,,, meening now i know what small areas need attention , so i am saying if primer looks good you still might have something going on underneith,, about 35 small spots on each side,, of boat mike :
