Yeah I am a roofer so it pretty much sucks being on a roof all day covered in shingle dust mixed with sweat, sunburn and dirt lol. Good money though and I don't mind my co-workers and boss. I also work at my dad's autobody shop. That's even more dirty. I hate spraying clear coat on cars it just burns your eyes and you get dizzy even with a respirator. Double action sanding sucks too lol your covered with clear coat, paint dust, plastic filler dust and all that good stuff. In that trade it's definatey worth it in the end. I love auto collision repair it's just some of the tasks aren't so great. I am in school right now for Auto collision. I would much rather work at the Mystic Aquarium in the state I live in. It's an awesome Aquarium! my favorite place to go.
