POR-15 Fuel / Petrol Tank Sealer High Performance 473ml US Pint

It's very strange stuff, metallic silver in colour, and it foams up as it hardens, so if you drain the excess back into the tin, it will not go in.You need to know this, because it is very difficult to get off whatever it spills onto.Clearly this is not a bad thing, because that means that it will not come off the inside of the tank either. Just be warned, and do not spill this on your living room carpet! (No of course I didn't- but I do now have a silver painted stool on the garage!)It does a good job and I can recommend it.

Great item purchased to repair fuel tank on vintage car, did the job perfectly and saved my dad hundreds of pounds a new tank !! thanks.

This is great, Seems to have fixed constant clogging of the carburettor. Although its an involved job, time well spend with this sealer

If your doing a motorcycle tank this is what you need you can hear it in the tank first tin was too small had no ideal if it had done the job good stuff

Does what it says on the tin. Most of the sealer is back in the tin and it has not yet gone solid! So will do other tanks. One application sorted out my leaking BMW tank!.

Worked very well, if needed would use again.

Great product, great price. Many thanks.

so far so good.It has sealed a leaky tank and is enough to do two motorcycle petrol tanks
