stripping black seam sealant
I must say the California plant did a great job sealing the rivet lines on my 60's trailer. Granted it was needed as the riveting was horrible but still there's little evidence of corrosion on the inside of the exterior skin. Now my quest is to remove all the black asphalt like sealer before tearing the trailer down. The 1st hurdle is that the stuff is immune to all known strippers….well so far I've managed to strip the seems on the aft end cap and it's a brutal task and my technique isn't going to cut it on the bows.
I've tried a bunch of the safe environmental stuff; bug and tar remover, WD40, 3M gasket stripper, Blast Off, Varsol and Acetone with mixed results.
I'm thinking of trying Heirloom heavy paint stripper tomorrow and if that fails ordering Citri strip which has to be shipped in quarts to me from the USA and thought it could't hurt to see of anyone has any tips.
In an ideal world I'm after something gel like that I can paint on, wait a few hours and give it a bit of a brush then hose off.
