I hadn't really considered all the different type of jobs-figured I could use it for pretty much everything, but what you're saying makes sense. I have an entire car to redo, but don't plan to blast anything big at home. I experimented with some chemical paint remover over the last couple of days- it seems to work fairly well. For rust, I have been using rusteco...which seems to work pretty well too. Rust comes off pretty easily with that stuff.
So far, I have only used the compressor with a small grinder with a wire wheel on it...it wouldn't run continuously, but it was more than 15-20 seconds. I just put in a dedicated circuit today, and plan to time it tomorrow. I'll let you know how it goes.
