POR-15

[HOrnbrod]

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?

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.

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:

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.
