Pete, bought my set up from Tractor Supply. Most are all about the same. Since I don't have REALLY DRY air I spent more time unclogging it than blasting on some days. I paid $225 for it and sold it for a $100 after I did my panel frame. Heck, at $4 or better for the good true blasting sand which is also sized, you can soak some money in sand along depending on how bad something is.
I'd think the inside of your bed would come off pretty easy.
Good luck.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
