I was able to remove all of the aluminum tape which wasn't terribly fun. I am pretty sure that all of the bid tapes will need to be trimmed down quite for the top skins to fit flush and before I start fitting the top skin I wanted an accurate thickness so I added the first skim coat to both skins. I REALLY do NOT recommend skimming with EZ Poxy unless it's inside the tanks. No matter how thin you apply it, it likes to pool up or orange peel really bad. I'm glad the only thing seeing this will be 100LL. For all else, definitely west systems.
