Picked up the HF non cabinet 110 psi unit today, I am going to build a wood framed box and line it with sheet metal, big enough to put a fender or a hood into it. It will be big enough to set up 4 wheels or multiple small parts.
I have to clean up 2 sets of rims so it was a no brainer to buy rather than pay for someone else to do it.
It looks like I will be seeking a powder coat machine as well.
