Help on gas tank restoration

[copo69]

I've got a '69 Biscayne and gas tank is in bad shape. Although it's not rusted through anywhere the tank has small rust particles in it. It would be best to replace it with a NOS tank as no one repros these tanks, but a NOS tank doesn't seem to exist. Any suggestions on how to clean tank? I don't know about boiling out tank as rubber neck is intregal part of tank and if it's destroyed. I see the do it yourself "kits" for doing this but I've heard of problems. I've also seen the RENU process but again I'm still leary. Brian, Mickey, or any of you ever ran into this problem? Finding stuff for these cars is tough. Thanks for your help. Greg
