Gas Tank Restore question

[bobswei]

I'm at the Gas Tank stage of my project and decided to strip the tank of it's undercoating. After an hour or two of Aircraft remover, a putty knife and disk grinder with a stiff wire wheel attachment, I only have the flat bottom section clean. Is there an other way to do this? I imagined about an hour to wire wheel the whole thing...
Thanks for any thoughts.

A new tank is a good idea but nothing wrong with the one I have.
Any other ideas??
Thanks.

why are you doing that in the first place?

Bosch or Wurth or somebody makes a giant power undercoating remover... but it ain't cheap.

I'd respray the undercoat you removed and put the tank back.

Thanks for the rsponses. I'll check into some of them.
The tank had some chips out of it and the spot repairs I did, did not match the original finish. Then I saw photos in "Original 911", and the early cars had smooth tanks (no undercoat). Hum?

I used paint remover to soften the rubberized coating then used a scraper. Worked great. I used the drill and wire-wheel to finish the spots that were really tenacious that I could not get off with the stripper. The stuff is very viscous and will burn if you get it on your skin, so work in a well ventilated area, apply with cheap brushes, where eye protection and allow the stuff to literally melt the coating in a short time. Any hardware store has it. Worked for me..

check with the concours experts on Early 911s BBS for what exactly your year and model tank "should" be like

I usually change things on my car to a newer improvement made years later, but some like to have museum like cars, i.e. exact preservation.

Good sugestions rwebb and sunroof. The early 911 guys would know what was proper for this vintage. I'm tying to get it all original but the pics I see have a smooth tank and I have one with undercoating. Maybe smooth is just a way to make it look very clean?
Thanks

Bob.
Glad to help.
I replaced the fuel lines from the tank to the tunnel and tunnel to the filter and return. The proper OEM line ain't cheap nor are the clamps, but you probably already know that. There is a foam rubber seal that weather proofs the tank at the bottom, but it was an expensive OEM item from the Porsche factory. What I learned later is that the same weather stripping for windows and doors for the home will suffice and 85% less!!!! Check Home Depot or Lowe's. Its a good time to clean, inspect and even paint the clamp down hardware for the tank as well and add a new gasket to the fuel level sending unit.

Overall I was extremely pleased with the finished product, which looked just as good as factory and showroom. The WURTH coating was great and restored texture, color and protection.

Thats all I got. Good luck with the project.
