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."

sounds like alot of rigamoro.

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 guess if you get something sodablasted, I can't imagine or can understand MORE steps for painting prep. Vinegar, etc. I would opt for a different media with less bs involved, IMHO.
