what to coat a tank with?

[stancotreau]

Hi, first let me introduce myself........ I am Stan from Billerica MA. I just bought a 1981 GL1100 to tinker with. it needs work but I have brought worse things back to life.

This is the first time I find myself dealing with a rusty tank, after I clean it out (vinegar? muriatic acid?, any ideas are welcome) I will need to seal the tank. I have heard of KREEM, but have also read cautions against using it.

So, if it was your bike what methods / products would you use to fix the cruddy, rusty tank?

thanks in advance...Stan

I haven't had to do this myself (thankfully), but I've read several different articles on doing it. I think the best one I read is from Randakk's site, where he has an article on tank refurbishment. In it, he recommends these products:

• Rustol from Sudco: http://www.sudco.com/
• RUSTECO: http://www.rusteco.com/
• MOTORCYCLE TANK REPAIR from POR: http://www.por15.com/
• GAS TANK SEALER FOR MOTORCYCLES from Eastwood: http://www.eastwoodco.com/

Randakk may be opinionated, but he's also usually right.

Had this problem with a 1200 LTD years ago. Found a guy who did it professionally. Just sit on the phone and ask around.

He cut out the rust and brazed the tank. Good as new and no risk of goo melting and clogging everything up. Best of Luck Dave in Western Australia

I have had good luck over the past 20 or so years using epoxy. It will encapsulate the rust, cuts off oxygen to the rust, so it doesn't continue to rust. Seals small pin holes. If you feel you have to clean the tank, use phosphoric acid. It leaves a coating on the rust so it won't flash rust when your done.
