Thanks everyone for your opinions.
Charlie: The direct pressure systems seem great but probably a little "overkill" for what I need. I still have the option of sending the real nasty stuff to our local media guy. I spend a lot of money annually on paint and rust removal. Currently I am hiring an apprentice in the shop and if I had a more efficient Sandblaster I can keep most of that blasting in house while having an extra body around the shop. As far as the TP Tool units, I've been looking at them. Their equipment seems fair priced for what you get. Can any of you using their units tell me how efficient and how noisy that style dust collection system is? Can you see fairly well what your blasting? Also, I know this is a loaded question but approx. how long would it take to Blast an average lower control arm? Thanks again for the advice! Don
