i have decided to just shut down july/aug from now on.i can work in the building / upholstery room since it has a/c . even with a 36 in fan my shop is around 115-120 . no paint booth work . my air chiller lets me media blast in the morning.
if i had it to do over i would build a sheetrocked type building with a 6 ton a/c .
i have been talking with an a/c guy about building a portable type unit.
