Anyone ever blast the paint off their car with baking soda and then have trouble getting the new paint to adhere even though the surface was washed several times?

Nothing to fear. Just prep the surface properly. No more work or steps needed if it was chemicaly striped or sand blasted. Just common sense.

Not trying to rob your post. I was wondering the same thing (almost). Which is better: soda blasting or media blasting?

Soda is by far the best for paint. Less chance of metal warpage ect. where more agressive media creates heat and can do damage. The after prep is just common sense. The problem as I see it with soda the panel looks brand spankin new once blasted and someone may want to just wipe and prime. Thats where the problem comes. It just needs to be properly prepped for primer etching.

My investigation led me to the conclusion that it depends on what condition the vehicle is. If it is a paint strip, Soda blasting is fine. If there is rust, media works better. One of the problems with soda is that I have read it can do funny things in the future. Soda is a basic, so I would have to think what I read refered to the fact that you must, and I repeat must, get all the soda out of the car after blasting. Soda can hold moisture and therefore lead to rust in the future. There were also major questions with how to clean the soda out, how many washes to do, any additives, etc. I believe I could have had the Barracuda blasted for about $800 but issues led me to choose media. My neighbor is a bodyman and he told me they had an Austin-Healey come and the guy came down with a portable plaster and did the work on site. I thought the Healey might be aluminum and he told me no it was regular metal and a lot of wood, and the job came out fine. For media, I plan on using glass bead. Not cheap, but it is non-porrous, tends to heat the metal much less than slag, and can get the rust as well as the paint. Hope my plans don't blow up in my face. I will be doing this in about 2 weeks.

I remember my dads 54 Austin Healey 100-4, being steel on top and the sides were aluminum.. Or maybe it was the other way around.. The magnetic strip on the flashlight would not stick is how he found out..
