I didn't have a good experience with this, but it was a water leak so there was some pressure. My concern about a gas tank is there will still be some pressure until the material it dries up and I don't know whether you'll be able to get a seal.

Mine leaked. You might need new gasket rings. Mine always broke and didn't seal completely.

yes if you dont have it screwed on tight gas will leak from around the threads could ignite. but you'll most likely smell and hear the gas before this happens.

It is a fuel additive ,so if it is sealed tightly it should be good fo a fairly long time.Otherwise it will evaporate and not be any good.

Mine didn't have a seal, and I didn't see any leaks. I didn't have it on during any hard reason though. Hope this helps.

try the simple thing first, clean the gas tank fill cap. If it's clogged it will impede your gas flow.

I've found that the sealant tends to seal its own can shut after one use. Others haven't had this experience.

It depends on the material you want to make leak proof. If the leak is small or narrow, the Flex Seal should work. It made need additional coating depending on the size and depth of the area to be covered. After totally dry it should be able to be painted.

This is good stuff but I would not recommend using it in a gas tank. I ordered two and they came in a plastic bag. Problem is that one of them leaked out all the contents so I got half of what I ordered! Good luck to you.

yes, I have painted and spray painted over flex shot. I have discovered I haven't been using a thick enough spray of flex shot to solve my leak problems. Hope this helps.

No. It shouldn't leak. It must be defective, There are no gaskets to insert,

Check the rubber gasket. If it is getting brittle, it will not seal. A cheap, easy fix.

I hope you get an answer since I was wondering that myself. I left mine in but used it again in the next day or so. It was always ready to fire. I think these other folks are correct because I am sure it would eventually leak out. I like the suggestions for enhancing the seal.

Probably, but check that the rubber gaskets aren't the problem. There's also the water line connection into the tank, which is where I've personally seen the most leak troubles. If it's been installed a while and just started leaking, then it's likely a rubber gasket issue which you should be able to replace for a couple bucks at any home improvement story.

yes make sure it is dry . I have even repaired Small gas tanks for lawn mowers

Yes as long as the gasket is in place and you completely screw it tight, it will not leak! I've turned my upside down many times or it has fallen and nothing leaked out.

It will seal ov err it but I brushed and coated mine with roofing paint and let dry before laying it down.
