Well guys I coated my first CFX carbon fiber grip and it turned out great! One question I had though was after applying my first coat of permagloss I had these little tiny air bubbles start showing up did another coat and it didn't do it again and was just curious what it was from?
Thanks Trace Re: Air bubbles on carbon fiber grip?

How did you apply the finish? Re: Air bubbles on carbon fiber grip?

The surface you were working on may not have been smooth, which means the top coat trapped air which then had to escape. If the surface isn't smooth, it may require you to seal it and then sand back down to level before top coating with PG, if the bubbles are an issue for you.

Try to apply permagloss at a cooler temperature. If its to warm the permagloss surface will start to cure to soon and will trap the gasses that need to escape during the curing process. We like to permagloss when its very cool or run the AC in the summer. Give it a try and hopefully it helps you. Re: Air bubbles on carbon fiber grip?

Never had problems with air bubbles when top coating a CFX grip with Permagloss. Are you sure they are bubbles and not dust?

Actually, it's moisture, not temperature, that causes PG to set more quickly. Warm air generally has more moisture in it than cool air, thus many assume it is the temperature rather than the moisture (humidity) that is making the difference. No doubt when you run the AC you're dropping the humidity in the room and that's what causes the PG to set more slowly. PG is a moisture curing urethane.

I know it's moisture curing but from all of our testing heat affects it as well. I'm on the west coast and the humidity is 70%-80% recently. I can take a batch of grips and permagloss them when the temp is around 55 degrees (80% humidity) and the grips will be perfect. I can then heat the shop up to 80 degrees and permagloss a batch of grips and every one of them will have small pin hole air bubbles. The only thing that changed is the temp unless you can calculate how much moisture in the air has changed. The high humidity with cooler outside temperature equals perfect finish and 90 degrees in the summer with almost zero humidity here on the west coast equals bubbles. Kind of goes against the humidity with regards to bubbles forming. Re: Air bubbles on carbon fiber grip?

Thanks for the replys guys! I think tom was might have hit it spot on though I never sanded the grip smooth and i was in the garage with no heater. But yes norm they were very very tiny and you could pop them. There was not a whole of them just kind of came at random it looked like.
