POR-15 - 49204 U. S. Standard Tank Sealer

100 percent worth it. Worked excellent

I recently restored a 300 gallon fuel tank for my farm and wanted to clean out the inside of it as well. After extensively washing the inside of it out the best I could I poured 1 1/2-one quart cans of this sealer into the tank and it turned out awesome. The product, being so thin made it easy to disperse inside the large tank and coated the tank very well. Very happy with the result. P. S. Don’t get it on your hands, very difficult to get off.

Seemed to work well, time will tell. Poured well, not too thick or thin.

Used on a small generator tank. Follow instructions exactly. First try I didn't drain enough POR15 and it failed because of puddling. Very tough to remove it. Used aircraft paint stripper and heat. Second try I drained for the recommended 30 min. Coating appeared thinner than I would like but tank is holding gas with no leaks. Good product. Just make sure to do a good prep on tank first.

Product did exactly what I needed it to, coat the inside of old fuel tanks to prevent future rusting. Seemed to go on kind of thin and had most of the can come back out after coating but cured well and seems perfect.
