Sticky for sure! I use brake cleen on cars all day at work. I work at a transmission shop and thats all we use cause it doesnt leave a residue after it dries. We use it to clean parts for assembly, Undersides of cars, and prep for welding. But fuck that shit.
I dont think its using brake cleaner thats the problem. Its brake cleaner plus welding that creates the problem. The problem is ignorance. I mean really, you think fiberglass dust finds its way out of your lungs? No. You think your vision will magically come back after 20yrs of welding. No. Part of life. Chose your ride wisely cuz you only get 1 ticket!
