I'm having a big problem with a finish I'm exparamenting with. I've just started using U-40 Perma Gloss. I like the finish and the ease of application my only problem is after the first coat is dry I apply a second coat. As the second coat is curing/drying it bubbles then lifts off the thread. I'm using Flex Coat CP on the threads before putting on the U-40. I was able to save the wrap the first time now I may have to do it over. Is there anything I did wrong or do I need to use the U-40 Color Lock? Thank you for your help

Hi Randy-

Based on my limited experience using this U-40 Perma Gloss as a thread wrap coating, it sounds like the first coat needs to dry a bit longer. I believe the bubbles in the second coat are from the remaining solvent (from the first coat) trying to escape, and forming bubbles in the second coat. Hope this helps!

I've been using Perma Gloss on bamboo, no problems and able to reapply after 1 hour. I apply very thin, takes 4-6 coats. I don't use cp but they say to use Color Lock if a cp preferred.

I agree with Jim. Keep in mind on your first coat that U-40 should be applied very thin. It's not like Flex Coat where you're trying to get a good build in one application. It's okay to drag the brush when using U-40 and your build-up will come from many applications (4 - 6). I had the same problem for a while. When I applied the second coat it seemed like the first coat would bubble up and peel off like a curing sunburn. If you apply it real thin you should be able to apply the second coat within 30 min. to an hour. Get this. When I apply it to bare blanks, as a clear coat, I can reapply in 10 minutes or less. If you apply it thin enough, you will notice that there is no need for turning the rod with a drying motor. This is when you know that you're on the right track.
