Applying POR-15 Fuel Tank Sealer (True Spirit # 42)

[@hid3nax]

Perfect video on how NOT to use POR15 fuel tank sealer. First of all, you must use POR15 degreaser and then metal activator from their product line to achieve best results, not just random brake cleaner. Your tank is new and not greasy? Haha... What about leftover flux from soldering at the factory, etc? Also, you should never never ever shake POR15 fuel tank sealer. It introduces air bubbles. You must open the can and stir it well until it becomes uniform in colour. From your example we see it wasn't uniform colour. I wouldn't expect great and lasting result of this job

10/10! We all appreciate your expert advice and look forward to the video.

I did this on an old tractor tank a few years ago. It was not POR15, different brand, but it did not work at all. Despite following the instructions exactly, I'm still dealing with the epoxy chunks peeling off inside and the rust is worse now. I hope yours works out better than mine.

That doesn't instill confidence. I hope I have better luck as well.

@@YoshimoshiGarage I think the biggest issue was it was impossible to get the epoxy onto the baffles, so they were left untreated and I'm sure that's where the peeling started and progressed from there.

same here with several M/C tanks all peeled ...interesting thing was on a split HD tank one side peeled other didn't other set done at same time by another person same product did the same ...I have a theory that the etching agent loses its strength after doing the first half

any updates on how the gas tank is now? i know the video is a month old, but im about to do the same thing to my metal gas tank, just wanted to see how well it’s holding up for you

[@moparnut6286]

Just wondering how long it will last when exposed to fuel....ethanol and the additives they use in today's gas is the main culprit for moisture absorption.... I have done boats where I pulled over 5 gallons of water mixed in the fuel... Pure gasoline does not absorb as much water from the air as E10 or become as corrosive as quickly.

We'll see, but it's got to be better than raw steel. I hope, anyway

@@YoshimoshiGarage have a friend who does this professionally and he is VERY expensive to the point you would rather buy or make another tank
