Soda blasting won't get rust off. I don't know how old your hot rod is but i thought i'd give you headsup in case you didn't know and committed to something that won't do you much good.

i am very fortunate in that i do not have alot of rust. i was interested in how easy it looked with getting paint off to the bare metal.

Barb - the problem with soda blasting is that many, not all, undercoats will not adhere well afterwards. Make sure what you plan on using is compatible with soda blast.

What happens is that the soda "hides out" in the tiny base steel microscopic pits and crevasses that happen after any media blast and wont allow proper paint adherence to the body panels - and you can guess what happens to your mega buck/hour paint job.

thanks dave that is the knowledge that i was looking for.

I asked a sandblaster/sodablaster who did work for us at the marina one time about doing some sodablasting on some sheet metal I had. He said exactly what Dave did, that he only likes doing it on fiberglass because it doesn't properly prep the surface of metal for painting. I've read since about adhesion problems when it has been done.

thanks don.

We don't use soda for those same reasons.

Aluminum oxide is the best thing going right now, removes everything, and below 60 psi will not hurt body panels, unless you focus on one spot for a long period of time.
