I'm not sure I would brag about it. I'm no better because I used to work repairing fiberglass panels. As in, grind the stuff smooth with a sander. If it was just a "little" bit, I didn't even use a mask. The stuff is nasty though and I wouldn't be surprised to someday see it classified as a lung cancer cause. You know, kinda like asbestos used to be commonly used and now, not so much. I've worked with both during my life and now, I would not recommend either.
