Fuel tank restoration

About 25 years ago, I pulled the tank out of my 69 Barracuda. It was really NASTY inside, but they were not making new tanks for them back then (at least not that I could find). I bought a fuel tank restoration kit from Eastwood. I followed the instructions exactly. One step was to clean the tank out with Muratic acid. Be real careful with that step. Then I mixed up the epoxy that came with the kit and poured it in. Then I spent about 15 minutes twisting, turning, tipping and wiggling the tank to ensure even coverage inside. It then looked great inside. That treatment lasted about 15 or so years. When I blew the car apart again for another paint job about 9 years ago, I bought a new fuel tank. Believe it or not, the old one still looked great on the inside. I can highly recommend the Eastwood kit.
