I have used the Perma-Gloss on two rods now. Works well. Haven't had it long enough to check out the shelf life.

It took several more coats to fill the thread, but the coats set up in less than an hour.

Read the instuctions for all the details. Failing to allow enough cure time between coats will cause bubbles in the finish.

I haven't found a way to clean it out of the paint brushes I used, so I went through a lot of brushes (epoxy cleans up just fine with vinegar)
