Out of the three methods, dustless sandblasting is better for steel because the water in it reduces friction and heat, which can warp the metal during the stripping process. According to Dustless Blasting, the original manufacturer of dustless sandblasting equipment, dustless sandblasting can actually lower the temperature of the metal by 10 degrees while the process is being performed.
Some people have taken to applying a cooler to the sand during this work to help mitigate this effect. The first step in the process is for a car owner to figure out which parts of the vehicle body need to be blasted.
According to eHow, if sandblasting is being employed and the part being blasted is an underbody part, a bleached and washed sand should be used. For visible surface parts, such as door panels, grit silica sand should be utilized.
If possible, parts of the car not being blasted should be removed and kept in isolation. These include panel strips, door handles, taillights and other parts that are not undergoing the refinishing process.
Contrary to popular belief, taping over parts is not a good enough solution because the particles may erode the tape or get underneath it. If possible, the parts being blasted should themselves be isolated, and a tarp should be used underneath to catch the particles and dust.
Dustless Blasting claims that dustless sandblasting is faster and easier than soda blasting. On the other hand, as far as cleanup, soda particles can typically be washed away whereas sand and dustless sand particles can be recycled and need much more cleanup time.
According to Jalopy Journal, in many cases, the sand or soda can stay in joints and cracks of the car body long after the work has been performed. For this reason, extra attention should be paid to holes, nooks and crannies in the areas being worked on.
Soda blasting and sandblasting create dust, which can get inside the vehicle and into body parts. Baking soda is technically an alkaline chemical, and the particles are so small that they get into the pores of the metal. Therefore, to remove this film, grinding must be used, or the film can be neutralized with warm, soapy water and a scuff pad. Some people perform the latter process at a car wash. I have no direct experience with it but my research has come up with soda blasting being more than worth the money.

It did the job as far as the metal goes. Just take ever thing out of the car. Joined: Sep 13, Posts: 4, Profile Page. What is this place in Sac.? A bit far for me, but I need some stuff done too and if they do a good job, maybe worth the trip.

Have had a couple of cars soda blasted does an excellent job-very clean with no warpage--only way for me-Precision Stripping in Lodi is the place and they do outstanding powder coating as well. Thanks for all the advise so far. Here is the info for the company I talked to. I'll be sure to check with the company in Lodi. Thanks for the heads-up. Sorry I forgot the company info.

I have also heard a lot of bad things about "media" staying in cracks and joints for all of eternity. Any thoughts? Last edited: Jan 8, Joined: Apr 15, Posts: 6, Profile Page.
I worked at YearOne when that happened. I also know the shop that did the soda blasting. The soda blaster and I have talked extensively about this. I don't know what the stuff is, but he now sends every car out the door with a gallon of neutralizer. Now he includes it in the price, and paint companies WILL warranty their product if a soda blasted car has been neutralized with this.
When the YO car was blasted, he was selling the neutralizer at his shop, it wasn't included in the price of blasting small business starting up Well, YO didn't buy the stuff, because they know what they're doing in the shop, they've been painting cars for years, we don't need to spend any more money with you, and the result was paint lifting. Seems you can't just use a DA and sand off the protective coating left by soda blasting In my small town there is the Soda Blaster, a sand blaster that YO uses , and there's also another media blaster about 45 minutes away that YO uses for bodies.

I was saying that if i had it to do over again, after seeing all that crud come out, i would dip it and figure out some way to spray protection down the frame rails.

People never come out entirely happy with either method. There's one thing you can take to the bank: Either method can ruin a car if not done properly. Either one needs to be done by someone who specializes in using that method to strip cars. Don't just go with someone who uses that stripping method for various industrial purposes and is willing to do your car. If I had to do it over, I'd let him supply that.
I think it was a couple of hundred extra if he supplied it. I was a little concerned with panel warpage. When I went by to talk to him initially, he had a car sitting ouside that he just finished. It looked fine to me. And mine came out fine too. In fact, he told me that my unibody was one of the best three that he has ever blasted.
Their place isn't the prettiest or the cleanest but they worked with me and did a good job. Helped me unload my car from the float, helped me load it, and also met me on a Sunday when they are normally closed. Very nice and friendly folks and willing to work with me any way they could. I recommend them. They have been on tv on PowerBlock since they are pretty close to Nashville. That's actually how I heard of them.
Although they said they spent 3 hours blowing crushed glass out of frame rails, rockers, etc. And I'm sure that we even now don't really have all of it out. But whats left I think I can live with. I have had my body man install weld in frame rails that weld to the floor and torque boxes.
Also installed a 11 gauge steel lower radiator support. When it comes to stripping our Corvettes down to the bare basics, there are three options: chemical strippers, by hand with sandpaper and other tools, and media blasting. Obviously chemical paint removers aren't the first choice. When you're talking about stripping the paint from a Vette, chemical agents are always discussed, with the same conclusion: not many people trust them. Let's face it-fiberglass isn't steel, so there's a pretty good chance a chemical stripper will either attack the fiberglass, or seep into it and ruin any chance of achieving a good paintjob down the road.
Manually, you can use sandpaper either mounted on a dual-action sander and "jitterbugs," sanding blocks and contoured sanding pads, razor blades, or our personal favorite method, a wet sponge and baking soda. Sanding a car by hand gets the job done, but it's not only time-consuming, it's incomplete: You don't typically get inside the trunk or body, under the hood, and so on.
We've actually seen whole cars stripped with razor blades, and it's not nearly as hellish as it sounds. Once you get a good rhythm going and the razor's angle of attack right, it goes pretty quickly.
And for fun, you can sweep all the flakes into a bag and weigh how much paint your car had on it! But sanding the car or giving it a close shave really only hits the easy spots-the exterior surfaces, the doorjambs, and maybe a couple hidden areas if you're aggressive.
And heaven help you if the car is wearing several layers of paint stacked on one another. That's why media blasting is one of the best methods of stripping Corvettes. There are some serious concerns with this approach, though, mainly that it can destroy the car if done improperly.
