The Stovebolt Site Forums The Shop Area Paint and Body Shop pressure or siphon blaster??

I have both also. The experience is the same on the siphon as the others but will do most smaller jobs with only your time spent.
My presurized blaster clogs a lot to. Sometimes I can go through a 100 lb bag of sand and never have a clog. The next time I may have half a dozen trying to use a bag....and I use the "sized" stuff. (3.38 per 50lb bag)...I think the clogs come from moisture in the air. I KNOW I do NOT have a really dry air supply so I have to live with it. I have an 80 gal, 7hp set up but didn't do enough plumbing to keep the air really dry.
Folks who use the same blaster I do and NEVER havea problem has a somewhat "elaborate" plumbing/drying system.

My personal advice is depends on how much you plan to use it. If its a one truck restoration deal then take your stuff to a sand blaster (some experienced monument places are good) and have them blast your parts. Considering the cost of the blaster, sand and your time and aggravation you will be better off.
*** I just sold my presurized pot!! I used it last summer and that was enough. I did keep my siphon blaster for parts that won't go in my blasting cabinet but no more BIG jobs. Not worth the hassle for the amount you spend vs what you save.
