I found a cheap sand blast nozzle (at Harbor Freight) that holds 9 oz of media in a hopper right on top of the gun - connects to the air hose and has a nice little handle for tight spots. Has anyone else used anything like this before? I don't want/need a big set up. I just have some small areas to work on and want to get the frame rails and bottom side of the floor pans before I hit it all with some paint.

Now that being said - they have another nice little setup that I wouldn't mind picking up. Has anyone got one of these?

I've got both and they are alright but stay away from sand if at all possible. You can get other blasting materials right from harborfreight. The presure pot works well but you go through alot of material in a short time unless you can collect it and screen it to use over. If you have water in your air lines your going to hate blasting as it will clog up often with wet material. For frame rails I would use the pressure put and for small spots use the hand held unit.

Thanks for the quick reply. Do you happen to have a blasting cabinet from HF as well? If so - what do you recommend there?

What kind of media is recommended for the following?

Frame rail/control arms/rear end housing?

Inner fenders?

Firewall?

Engine parts?

Sand is the best thing to use on rusty steel parts like control arms, brackets/pulleys, etc. I have both a syphon feed hopper type blaster and a blast cabinet. The blast cabinet has paid for itself many times over since I've had it. If you do use sand, make sure you use a respirator. Silica is some nasty stuff to breathe in.

that gun you showed is a POS some one gave me one and a threw it out.

The speed Blaster, spot blaster is a much nicer version of a spot blaster, however its still only for very minor jobs.
