CAn I use fiberglass for gas tank repair

I have a gas tank I like to use for one more season (winter)

It leaks from having a plastic cover on it I removed it and have it upside down and wirebrushed ..sanded it clean can I use

The fiberglass material on it (the type that looks like cheese clouth)

Thanks for the info ..DANiel

 

We used to use glass on punctured oil pans when I was still living in the rain forest. Works like a champ.

 

Fiberglass will last for a short time.If you fiberglass the outside then use that stuff you slosh around inside the tank( Eastwood or POR 15 brands) it will be fixed forever.

PS sounds like it on a bronco!!lol

 

jb weld works good too if you clean it very good first and can let it sit around for a day or so after

 

polyester resin doesnt really like to stick to bare metal, epoxy resin on the other hand does. but epoxy take a long time to cure and is hard to get to stay in place because it wants to flow out. i have use jb weld on a few that are still holding after years of use.

 

Used regular old gas tank repair kit on son's car 2 years ago and still holding fine.Picked it up at N.A.P.A. Tried the epoxy stuff 1st,lasted about a month before leaking again.

 

We used to get 6 months minimum out of a glass repair on a tank. Most of the guys were working on a 6 month visa and I knew several that roached their tanks within a few days of getting down. I used to tell them to get it welded or replaced before they came back.

 

Take it to a good rad shop, and have them solder it.

 

In the old days I saw glass used, but with Ethanol in today's gas, even the 10%, the repair will not work. It becomes soft and gummy and starts to leak pretty damn quick. Do a search for boat gas tank problems and you'll see what i am talking about.

 

Although there are different types of epoxy resin, epoxy is also generally more chemical resistant than polyester.

 

best option

 

Beware of gas tank slushing compounds with todays ethanol gas. I used the Fuller O'Brien aircraft slushing compound in my 31 A (dash board)tank back in '78 and it lasted well into the 2000's. THEN the NEW CA gas came available and it started to eat the stuff out of the tank. Gummed up the 1850 carb in a week or two, had to take it apart an clean with acetone every week or so. Finally gave up and put a aluminum fuel cell in to solve the problem.
