Soda, leaves a film that must be neutralized. (not easily done!)
You want no part of it.
Go with the media.

There are many past posts on this subject explaining this, if this answer is not convincing.

Soda (baking soda, in simple terms) is a one time use product. It fractures. If it is not 110% cleaned off the surface, and every crevice, it will react with the paint. You ought to see what it does to PPG DP90LF after a week of it being on. Me, always having to see things for myself, blasted a section of an old wagon. (CLosest junk I had) Thought I cleaned it well with DX330, and shot some DP on it. Looked OK when I did it. There wasn't much left of it on the wagon when I took it to the dump. Think Baking Soda and Vinegar.

Soda is good for PAINT removal only. No rust.


Some time ago, I considered building a shop that specialized in Soda blasting. No one around does it. After a ton of research, I found that you really couldn't make any money at it. Bodyshops will D/A a car off, in less time than it takes to blast, clean and neutralize the car.

The biggest thing I found so far(as a newbie) ......take a tried and true method (sanding), and get right to it. Mediablasting can save time in COMPLEX areas with a lot of shape, but YOU STILL HAVE TO BE CAREFUL! The media is being shot at the car under pressure. Pressure distorts metal to some degree. Think not? Aim just your air nozzle at a soda can, and give it a blast. And thats just AIR. Now add mass to the equation.

The more you look for an easy way, the longer it takes, and the more aggravating it becomes.

media blasting is done at low presure /high volume. i use platic to remove paint and some surface rust. i switch to starblast to get the rust spots or when doing a frame. once you've stripped.......you'll never go back. it is unbelievable how nice it is to work with clean sheet metal. it cuts prep time to nothing. and painters hate prep
