|swvalcon||I've worked on two cars in last year that had metal damage from sand blasting. Only sand blast in door jams and places where it wont show. I did do a little blasting on the rear fenders of my 64 stude but they are really thick and I was very carefull with it. I wouldn't use soda either. Most of my paint stripping is done with 40 or 36 on a da both 6 and 8".|

|Trucknut||I've stripped plenty of cars. It seems to me that almost all strippers today claim to be "aircraft" strippers. Well, I've stripped and painted a few airplanes, also. My best advice would be to tell you not to go cheap on the stripper. Just like anything else, you get what you pay for. I use JASCO Premium Paint & Epoxy remover. Cost is about $31.00 a gallon at Lowe's and it works very well. If you apply it according to the directions and what's been said on this thread, you should do well. After stripping I use 80 grit to clean it up with a random orbital. Just remember to give the stripper time to do what it does. And, as mentioned, don't let it dry on the panels. If it does you'll end up loading up a lot of sand paper trying to get it off. I usually wash mine down with lacquer thinner after scraping.|

When some experenced painters swear by a product that I am having trouble with, I have to assume it is a problem with some part of my procedure.
But if there are several others that also have trouble with the same product, then I my have to decide if the benifits of that product are worth the effort to me, or if there might be another product that will give me what I am looking for.
And it is usually just a matter of learning how to use the product properly.

Soda is alkaline in nature and most primers are acidic so if any soda residue is present it will neutralize the acid in the primer and then the paint does not stick..Some guys have somehow escaped this issue but a lot have not and tha tis why we do not recommend soda.

He is referring to the paint manufacturer, not a painter. The paint manufacturer, every paint manufacturer I know of says DO NOT use soda stripping.
And like sand blasting it "can" be done, there are people who have sand blasted sheet metal for years without destroying it, so it can be done. But the overall majority of times it causes irreversible damage (or close to irreversible).
So what is happening is your painter is getting around this very difficult problem of the soda embedded in the metal, he is neutralizing it properly. If he didn't you WOULD know, we are talking total and complete catastrophic failure.

Back when I used to have parts chemically stripped by a shop who would dunk them in a big vat full of nasty chemicals we had lots of problems with paint sticking because parts would come out too smooth and sometimes it was a pain in the *** to get it out of hidden areas.
We used to have to sand every square inch of a part inside and out just to get primer to stick after the chemical stripping

|zmaxmotorsports||Ive had decent luck stripping sheetmetal with a soda blaster,takes a while but its much easier on the metal|

There is a lot of info here on hotrodders in the Wiki Section. , My willys had about 6 coats of paint and I scraped the top layers off, a lot of chips, no gooey mess until I got down to the bottom layer and used stripper. I also use my 3500 Psi pressure washer, to remove the stripper-paint that doesn't come off easy with a scraper. It will remove a lot of paint just slower, I also have a wet blaster from northern tool for heaver metal parts, frames ,axles, etc. water and sand, NO dust, just a wet mess, I had my nash roadster blasted by a guy the restorations guys use. He knows what he is doing and doesn't warp panels but cannot get out all the pits in sheet metal.
