as long as you ONLY powder coat in there, I don't see a problem with it. A blast cabinet never used for blasting doesn't know it's not being used for it's intended purpose. After all.... it's just a box I suppose. Does gasoline care if it's only going in my plymouth and not somebody else's chevy? nope... it just is what it is, right? Square box to do with what you will... blast, powder coat, cook grilled cheese in... it's all the same. Just don't mix one with the other is all. If yer gonna blast in it.... then ONLY blast. If you're going to coat in it... then only coat. If you mix the two, then almost always blast dust will be in your coating, and powder from coating will be embedded into your blasted part. Otherwise.... it's all good.
