Fuel tank fix!!!!!!!!!!

After getting my 69 Dart swinger 340 driving again [more than moving around body shop, or driving around block] and started having fuel starvation problems. Blowing air backwards usually cured it but the time in between kept getting shorter. So I pulled tank out and it had so much rust that I couldn't understand how it ran at all, I asked people what would de-rust the tank, well I settled on a derusting product by RUSTOLEUM, I will say that this is a superior product not only did it work fast but it had the inside of the looking like brand new. Just wanted to share that for all of us people who work on getting old cars up and running!!!!
