HOrnbrod Posted March 7, 2012 Share Posted March 7, 2012 I guess this is tech. :dunno: I don't have a lot of experience with POR-15. I applied a thin coat of it on the bike gas tank fill inner neck where I had a Monza gas cap brazed on. I left the cap open and the tank has no fuel in it. This was four days ago, and the POR-15 is still tacky, hardly drying out at all. Is this normal for this stuff? Link to comment Share on other sites More sharing options...
flint54 Posted March 7, 2012 Share Posted March 7, 2012 Nope. My experience, after using several different batches, on a number of different surfaces, in several different Wx conditions, is all the same. The coating becomes tack free in 4 to 6 hours, and diamond hard in 12-24 hours. In fact, I've grown to hate POR-15 because it cures too easily. I have wasted more product than I've used because, once opened, it cures in the can. I've tried saran wrap under the lid, and that was only marginally effective. I complained to their tech folks. The were kind enough to at least reply, and informed me that moisture in the air was what enabled/triggered the curing process, and offered my next batch with free shipping. I suspect you've either got a bad batch, or some residual contamination on the surface. Link to comment Share on other sites More sharing options...
HOrnbrod Posted March 7, 2012 Author Share Posted March 7, 2012 Strange. The metal is new clean metal, no corrosion, and I cleaned it well with POR-15 solvent before applying. I'm thinking the gas fumes still present in the tank might be causing it not to cure. :dunno: Link to comment Share on other sites More sharing options...
1987Comanche Posted March 7, 2012 Share Posted March 7, 2012 The floors in my '90 took forever to dry. They were tacky within a day. I waited all weekend and they were still sort of tacky. Finally had no choice but to drive the truck. One day of being in a hot, sunny parking lot with no carpet finished drying it. Link to comment Share on other sites More sharing options...
