no actually is patheticallly easy, there is no need for a respriator too, the material isnt very airborne (despite the looks of the pics), in fact they're not even required to use a high volume filtration fitler or anything, just some fiberglass filters exhausted to atmosphere.
It typically costs me $20 a box to do this, since there is no pot life for the process I get done. Its 3 part mixed while is sprayed so it doesnt require any waste. Win-win situation.
In fact all this talk fo this agian makes me wanna take my new box for my jeep to get sprayed!
