I like soda as a medium. Soda is pretty gentle, maybe too gentle for the underside of the car, but it will do the job eventually. Also, if it gets sandwiched inside two pieces of metal or metal and fiberglass, any moisture will cause it to expand and distort the metal or fiberglass pieces.

I like PolyPlus plastic media. It comes in different grits. I used to use it to media blast the flight controls on an A-10 aircraft. In the right hands, it won't damage anything under the car.

I think somewhere on this forum there is a thread with two body shop guys arguing back and forth over soda. Some claim some primers won't stick to a body prepped by it. Others swear by it.

I've done a substantial amount of media blasting and I doubt baking soda will do the trick. Ok for paint but I would imagine corrosion is out of the question. I will not say that for absolute sure since I only used plastic, glass, sand media, but it wouldn't be my choice. Plastic media is a no go on corrosion. Glass beads or sand will remove corrosion. I'm assuming that is what you are trying to do.

Thanks for the info......the car is 47 yrs old and I don't want to do any damage. I'd like to clean it up some but maybe will just leave it since ya never see it. The paint is good on the body, it runs great. Sat for years in a garage never even cranked. We put a battery on her and she fired right up. Amazing!!!! Thanks again.....

i like the media also. spi states right in their instructions to "never spray spi epoxy primer over a soda blasted vehicle" that is all the warning i needed.

It was done on my car and did a beautiful job of taking off the finish. However, the residue is a nightmare and I'd never do it again. 8 months later, I'm still cleaning baking soda off of everything each time I drive over 35 MPH! With a black interior, you can imagine the mess. It is caked into ducts and every possible crevas.
