What type abrasive and grit would you try on a truck cab and what pressure, nozzle size ect?
It depends on a lot of things/ preference so its kind of tough to answer. Most people use soda blasting for the outside body because other abrasives can warp & roughen up the sheet metal too much.
I think if you sandblast at a low enough pressure when it just starts to take the paint off, you might be fine with garnet, aluminum oxide, or glass beads. Use at your own risk though.
Other safer options similar to soda blasting are plastic abrasive or possibly walnut shell.
Nozzle size would depend on the size of your abrasive and the amount of CFM output from your air compressor. I have been referencing this air compressor pressure pot chart for matching the right nozzle size per compressor CFM rating.
Different paints and thicknesses of rust vary so start a lower psi and work up until it cleans effectively.
I hope that helps.

I have found a media called black damiond, it works good to remove paint and body filler from the body of my truck, I have tryed Baking soda media, it works good too, the baking soda cleans the metal a little nicer than the black damiond. I feel both work good, dam a big mess to clean up when you get done. I was wondering if anyone has tryed mixing 2- different media’s together, what results did you get, I want to try mixing the black damiond & baking soda media together just to see what happens.
If anyone has done it please let me know how it went for you, and I’ll try to post the results when I do it myself. Thanks
Hi Edward, I have not tried to mix them but sounds like a good idea to try out.
Maybe try a 3:1 ratio with more baking soda than black diamond. I feel like if it was 50/50 that it wouldn’t look much different, but I have no idea.
So feel free to keep us updated. Also, if anyone has tried this, let us know.
Thanks
