Stripping a 911 fuel tank
Does anyone have a neat trick for removing the rubbery coating on a fuel tank?

After my tank was cleaned out and absolutely NO fumes remained, I was able to use a blowtorch / scraper combination to heat and strip the coating. I then used a wire wheel to remove any residue / rust.
Worked fine, but again I must stress the need to remove all traces of fuel / fumes before even contemplating this method  Regards, Andrew M

I once burn my eyebrows playing with an old empy can of fuel... Before you take out a torch, find a place where they will clean a fuel tank(diping process). Everything will be clean, all the tar/protective coating will come out. It cost around $ 40.00 to do that.

It depends on the year but the early CIS metal tanks '73.5 and on cannot be dipped in a solvent like cleaner as they have plastic baffles inside that will dissolve. The outer rubbery (PVC?) coating is a Wurth product called Stoneguard. It can be removed with a powered wire brush; Wurth makes a special brush attachment with hook like wires that does an even better job. I was able to wire brush (rotary type in an air powered die grinder-wear safety glasses, face shield and gloves!) off sections that were loose or rusty. Then I applied Corroless rust conversion primer over the rusty sections and seam areas. This was followed by a respray of the Stoneguard (available in black, gray and beige?); this requires a special gun (available from Wurth) to get the OEM texture. I used the gray to return to the original appearance. Came out looking great! Jim

Thanks these are good tips. The tank was from an SC that burned. So part of the coating has aready been torched. I'll probably finish burning it off and paint it with POR15 as this car wont be in any danger of being caught at a concours d'elegance. It is nice to know that coating is available from wurth it sure is some tough stuff.
