Dealing with rust

Here is a photo of a home made sand blast cabinet I built this summer.  It's basically a re-purpased corner kitchen cabinet that has had it's shelves removed.  I added a re-purpased glass door and an exterior light for visibillity.  The gun is from Harbor Freight and cost around $20.  If you want to build this, it's easy.  Just seal it up first before you get blasting.  Better yet, put it on rollers and use it outside.  The better the ventillation the better.
