The $120 HF blast cabinet does need some work.I really wish i had room in my garage for a cabinet but I don't. I'd use the heck out of it for sure. Had to get creative with the tub. I just put a tarp and some lumber over it when i'm not using it and stays dry. Heard you definitely need to do some work to the seals on the HF cabinets if you don't want an eventual mess.
Silicosis.....the new asbestosis.Never ever, ever, use sand regular sand to blast with.
One of the most dangerous health things you can do.
