"How Do You Prevent Gas Tank From Rusting"
 
   Hey Guys,
I have a Piaggio(vespa)Ciao which has a metal gas tank in the frame, I noticed it started to rust badly After sitting around for many years.is there anything I can do? Spray?
If i where to open hte whole thing up and oped the gas tank open(very pianful prosses, too nany boolts) and polishing down the rust spots would that stop rusting?
Or
would if I opened it up and standed down the rust and the gas tank became to thin could i weld on some more metal? In ther words would it still be strong?

Great Thanks In Your Reply!

   you cant open up the gas tank without cutting it. rust is caused by one thing. moisture. the only way to prevent rust is to keep the tank filled with a high octane gas. low octane gas is made primarily with alcohol, whic attracts water. filling the tank with gas, and adding a fuel stabilizer for storage, leaves no room in the tank for condensation to form. especially if you store the bike in a shed, or under a tarp which is the worst way to store anything.
if rusted badly, the tank can be cleaned up with a sand blaster or media blaster, cleaned out thoroughly, then kreem coated. not an easy job on a step thru model such as a ciao.

   Greetings, I restore about 4-5 rusty lined gas tanks per month for motorcycles. The best way to repair is treat the inside of the tank with a rust dissolver such as EXRUST by KANO LABS or RUSTOL is excellant. Then after the tank has been treated and dried you can coat the inside with a fuel tank coating liner called RED-KOTE by DAMOM CHEMICALS of OHIO. , allow to dry for several days and you should have a lifetime of a rust free fuel tank. good luck ,MIKE

Thanks for your reply, Don and Mike.

I was looking around the internet and here and there and I dought I will find any of those chemicals here in Chicago. The Sand blaster is a reality but it seems to troublesome. I am using your tips on keeping the gas tank full but for the winter I am drainining it.

I got an idea to use a drain cleaner, called Hot Power drain cleaner by Comstar that I picked up at Home Depot, it supposedly cleans the metal to the shine. I do have to becareful not to pour in too much because there is a violent reaction and it begins to foam and i don't want it too eat up my paint on the outside.
Any Ideas? Would this work?

I will keep you guys updated.

Thanks agian in reply.
