k, I'm professional auto applications big shops They do have a booth
that the car or truck rolls into. It has several rails on each side to BAKE the paint with UV lights. This causes the paint to lay out better and improves adhesion. . Drawback is : too much heat and your body work will shrink and or all spot putty used will show into the finish AND or the paint will sag right off the panels. same thing he's doing in a shade tree manor. as far as fumes I wouldn't do it in my house .. Unless U wanna get WHOOHOO !! depending on the paint used Some years ago it could kill U .. IMRON 4 one . reason : introducing the activtor into the paint creates an ICyanetic gas . same thing they use in the GAS CHAMBER. dryers force the solvents out of the paint =
VERY SICK , Imron headaches ,and nerve disorders years down the road .USE CAUTION ..
