Thanks for the advice Johnny. I sometimes combine the hairspay with the gel, didn't make much difference. I get quite a strong hold as is. If the unit fits properly, I sometimes just use a touch of water and I get a "vacuum" effect and it sticks right on. I haven't tried it with this system yet. For average "everyday" usage, I've never had a problem going this route.

If I'm going to be in a situation where I want some more security, like watersports for instance, then I'll throw some tape or glue onto it as well.

I travel extensively as well. I have no concerns about the security as I refuse to go in the machines anyways.

Thanks, I'm quite pleased with the way it's turned out. I agree that when the thinskin is done properly, there are no issues with the hairline.
