my main concern with the mek is reproductive damage is possible, but since i have all the kids i ever want it is no issue.
back in the early 80's in the military we used to use it with nothing more than a dust mask. maybe that is why my son is so weird. but seriously that stuff is very nasty so i have heavy rubber gloves and a full cartridge respirator when i use it now. i mostly use the brakecleaner since i get it for a song thru the day job.
