Grouse: Brake cleaner huh? I'll have to give that a try. Thanks!

As for the tape, I've tried the pink and the white. White never worked for me, but the pink I could get to somewhat work. I kinda gave up on it because it was more frustrating to me than it was worth.

I'm shooting several guns tomorrow. I guess I'll try the tape again in one and try the brake cleaner in another.
