Ran across this on the net using Dry Ice as a blast media. Has anyone seen this and what is it's advantage over soda or other solid media? Looks like it does great on the videos I've seen but they can be slanted. I have no idea of the cost either.
 
IMO dry ice is the best way to media blast a car........and soda blasting. :confu :confu

I do not have experience with the use of dry ice but if it is effective it sounds like a good alternative. Soda has BIG issues with residue that to me makes it a bad choice. I had my car done with "standard" types of media and it came out perfect. NO distortion, etc. and completely down to bare metal. The only reason I would think the dry ice might be better...I spent WEEKS vacuuming out the left over media. I still find pockets of it occasionally!
 
Yeah, I have to turn the car over and vacuum and do it again and again about 30 times and I still can't get it all out.
 
Back when I was working ( pipefitter for Ford Motor) they used it in the plant for cleaning. Blasting oily dirt and dust off equipment. I remember it not affecting the paint under the dirt. Not sure what kind of blaster it was or if there was any kind of adjustments to make it more affective. The only thing it left behind was the dirt.
 
I always thought that soda blasting was the next best thing.
I didn't warp/distortion the big panels IIRC.

It does do that but it can also cause serious problems with paint. The residue left behind needs to be thoroughly cleaned/removed. It's not as simple as just "hosing it down". That adds a lot of labor and cost to the process that other media do not require. If the dry ice method can remove material as effectively as common methods, I think it would win hands down.

The quality paint and panel shops in OZ wont touch a car that has been soda blasted.
They reckon its almost impossible to get rid of the residue and it can cause paint problems for years.
With paint costing 10 - 20k you dont want to risk blemishes appearing.

Bruno,
The big problem with Soda is that it is acidic and you have to nuetralise it.
Miss one little bit and you know what will happen in a couple of years!! :skul

Actually, soda is alkaline. That's why it fizzes when you pour vinegar (acid) in it.

What kind of machine would you use for dry ice blasting, and where would you get it in the form to use it in said machine?
 
How much? and any idea how far they go. I only blast the concave areas like post, around the trunk and pretty much all the engine bay. The rest I let the DA chew off.
