I knew about that but never seen it done. What kind of a profile does it leave?
Really only looking for info on paint adhesion to soda blasted metal. I have new heritage rear quarters rockers and floors, so rust is gone just looking to clean all the paint off the body without sandblasting it.
Here's what google turned up this morning:
This is a cut and paste from a Nova forum.
"Well I contacted Sherwin Williams Automotive paint and this is what Rose Gasper, Customer Service Rep, had to say. "Application of a primer with minimal acid congertration such as etching fillers, vinyl wash, or metal preps, will react with sobium bicarbonare. This will emit carbon dioxide potentially causing blistering of the paint and then total delamination of the paint and undercoats".
Then Rose Gasper wrote the following steps must be adhered to. Observe recommendations specified by the company that produces the soda and the maufacturer of the equipment used. Then before applying any refinish materials, thoroughly clean the surface with soap and water, preferably with a pressure washer, then dry. The third step is to inspect the surface for any white residue. If a residue is found repeat the second step. The last thing is after the surface is thoroughly clean, and no residue is found, follow manufactures specific recommendations for bare substrates.
I hope this answers any questions you may have."
The preceeding post in the same thread stated:
"Warm water and vinegar will remove the residue. I add in a red scotchbrite and have had great results with small parts. I havn't done a full car yet. I also don't know any paint company that is going to warranty a paint job. When I was painting full time we had a problem with a color and called the jobber, they did replace the paint but wouldn't cover our time wasted."
I have used soda blasting in some of my builds. The only thing you have to tell the person or shop doing the paint work is that it has to be completly free of dust etc. Then it has to be wiped down thouroghly with vinegar. If you try to wipe it with a cleaning solvent all it will do is smear. Vinegar first then prep solvent. It will stick and it leaves a baby butt smooth surface. It will not remove rust though. You will need to take care of that before or after soda blast.

Call them talk to Bill or Brian these are great guys to deal with and they will give you the straight from the horses mouth answer.
I do sodablasting I do a lot of blasting for the local body shops in my area. I have done vettes merceds old mercs etc. I am not a total expert but I got a pretty good resume. In answer to paint not sticking after sodablasting. I know all the jobs I have done you wash the car down warm water and dishwashing liquid or vinegar and water. It is no big deal. I highly recommend sodablasting over the other types of blasting. 1 you can rinse away soda it will displace 2 It is totally harmless to enviro 3 The finish is excellent. Don't get me wrong sand dose have it's place as dose other types of media's. The jobs I have done where I have encountered rust those areas where gonna get cut out. The areas that had just surface rust the body shops I worked with would use a DA on it and prep the area accordingly. Hope this helps you.I was considering soda blasting for cleaning the 40 body but I hear about paint not sticking to the metal after. Is there some type of metal prep that has to be used after blasting?
The 3m wipe down was the main ingredient . Another soda blaster said no prepping afterrolleyes. I know a lot about paint, but mostly on the industrial side, which can be applicable in the cruiser nation.Gee, 'Elk, thanks! As I recall, i have received some great paint advice from you in the past. You're a professional painter, aren't you?
