No reason in particular. I Googled "fuel tank sealer" and the POR-15 stuff was the first (and maybe only?) result. The reviews were almost all positive so I stopped looking.Originally Posted by ItHurtz
I think that's worse case scenerio. Imagine you got a 50 gallon diesel tank with a 2" fill hole sitting in a cool garage. It's going to take a long time for those VOC's to off-gass. I have an 18.5 gallon tank with a 4" opening at the top, a 2" filler tube and a 3/4" vent hole. Plenty of air flow. Plus I have it sitting in the 100° sun during the day, and a fan blowing at night. Less than 24 hours after application, I barely smell any fumes and it's hard to the touch.96hr cure times, holy sht.
