J-B weld?

[bigred1]

is J-B we,ld fuel resistant?like can it be used to patch small holes in gas tank?

[hotgas]

jb weld is fine for fuel tanks, as long as the tank is clean and diy when you aplly the epoxy, and let it cure, it will last for years, not too pretty though

[bigred1]

how long to cure before putting gas in? also should i rough up the surface or will it bond right to the tak?

[hotgas]

rough up the surface, make sure it is clean, no grease oil,ect, cure time depends on brand of epoxy, they are all much the same, i would let it cure for 24 hours though to be on the safe side

J-B weld work. But, if you live in the north the temp. change will crack it in time. I would get a year or two. Fiber glass body filler works better. Find the leak. sand, dent it in a little. Use a punch or nail.
Make the leak a hole. then force the filler in. It will bluge on the inside to help seal the tank. sand out side and paint. Should be ready to add gas in 2 or 3 Hr.

thanks for the info guys! right now looking for quick fix i went ahead and used J-B weld brand, it says to let cure for 4-6 hr. so i will give it 8-10hr before putting gas in it... i will let you know how it turns out! :D or :cry:

It will work fine, Its a good temp fix. :thumbsup:

the first time I used old school j-b after letting it cure over night I tested tank found more leaks :doh: so not wanting to wait that long again went to auto zone found j-b stick, it sets in 5 min and cures in 2hr :thumbsup: so far it's holding great now tank is back on and I got to ride it around a bit today:D

If you cant get a seal with JB go to your local automotive store and aske them about SEAL ALL. It comes in a tube and works great, nothing eats through it. You cant beat it for gas tank patches, even on full size vehicles.

careful with fiberglass body filler, it's polyester based. not near as chemical resistant (gas) as the jb weld....it's epoxy based.

Why don't you use POR-15 or redkote? its what it is designed for, clean the inside of your tank, pour it in,swirl, and drain you'll have a tank which lasts10 years in stead of 10 weeks its a PERMANENT repair not a temp fix.

how would that seal the leak though ? and then youd have it all over the inside of your tank? not just the affected area?

[darrel 632]

yea, its all over the inside of the tank about .1/2 mm thick, any that drips though rust holes is sandable and paintable and you never have to worry about the tank rusting from the inside out again. don't do it with pet****s and other stuff on the tank it's not good for them. I've done 4 tanks with 1 quart of redcote with no issues, just follow the instructions carefully.
