Anyone here ever used a media blaster ? I've got a S-10 Kingcab that had a sorry paint job just before I bought it several years ago and it would be alot of work to sand the thick cracked paint off it. I'm thinking about renting a media blaster to do the job. Whats best sand or glass , plastic beads ? If you used one take a guess at how many lbs. of material I would need to do the entire truck and inside the bed ?

Actually, the best media is either Walnut shells, or soda blasting, both will remove the paint with out damaging the metal. Sand blasting will leave the metal very rough, and will require sanding and filling primers to get the metal smooth again. We used a lot of soda blasting at the air port, but it was a must there, don't need sand blowing around aircraft. The soda, could just be washed down with water, and it dissolves completely.

 Life is like a hot bath. It feels good while you’re in it, but the longer you stay in, the more wrinkled you get. |

Joe I think air craft stripper and a high presure washer would be faster and cheaper,might check it out.

Hey Joe it is not wise to blast the larger flat panels. This will warp the metal. Paint stripper might be your best bet.

Lot of upsides & downsides to consider with each media choice.
Sand will take it down the cheapest & fastest, but good chance large panels will warp and all glass and chrome will have to be removed or protected. Not really that great unless your project is completely disassembled.
Soda will not harm glass, rubber, or chrome (metal) no masking needed, but special care to remove the residue and prep prior to primer. If all residue is not completely removed, the paint will not stick.
Again, unless project is disassembled, stripper is very messy. You can't buy the good stuff anymore just anywhere.
Walnut hulls don't go far, used mostly in a booth so you can recover and reuse.
I think I would just sand it down and prime one panel at a time, unless you have a week to work solid. Maybe hit a few tough places lightly with the blaster, especially where filler is needed.
