Need a blasting cabinet

I got the cheap floor standing model from Summit. It works good. You have to assemble it with common sense. I went through three tubes of black RTV putting it together, but it seals and holds a vacuum good. I also have an entire kit to upgrade it from that site @CudaChick1968 always talks about. Haven't gotten around to it yet, but it's comin. A cabinet is a cabinet. It's how you assemble it that counts. Nothing in the deestruckshuns said anything about using sealant, but I knew if I didn't it would leak like the Titanic. I am happy with it.
