Looking for fuel tank liner? FYI

3M’s AC240 Class B might be an answer. It’s a polysulfide adhesive and coating. Rubberyish. Using it for something else, but I was looking at the data sheet, and it looks like it’s rated for interior of aircraft fuel tanks, which are prob’ higher solvent laden than regular gasoline.

Wait, just read on SealPak’s website that it is NON-resistant to Ethanol…

delete this thread if needed, no polysulfide is good for common auto fuel.

bwahahaha ^^^ It’s all good riff42 :)… I was excited there for a moment though!
