Dry Ice blasting??

I never hear of anyone using Dry Ice Blasting. This process is the same as sand blasting or media blasting, but the only difference is that the Dry Ice evaporates and leaves no residue. Does not damage chrome or aluminum, and will strip the paint off but leaving the original base primer. ( go figure!) Dry Ice blasting works nice on undercoating, it strips it off just like paint, with no added time, because the dry ice changes the molecular properties of the undercoat, freezing the undercoat, making it brittle and the high pressure pops it off. I have attached several pictures. Cool process! Tim Morin
 
Dry Ice Blasting

Very nice...Engine compartment shows exactley what T.A.C. folks are looking for.(unprimed compoments,stitch welds,ect.):)
 
Don't

Get it in your shoes! Looks great. Please detail the process more. Sounds like it is a cool thing to do on a hot day too.

Does it come crushed in a big sack to be poured into where sand would go?

The Dry Ice as supplied comes in pellets, by the lb. and comes in bulk, weither sack, tub, or container. It is a special machine, and as I understand it, the west coast has many of these units out there. One of the Companies is: Cold Jet, check out the links and youtube. Tim

Looks like the way to go, no mess and no sand that comes flying out during paint ! I had a quote recently to do a 65 mustang , but the price was upwards of 5K . Not in the budget on that car. Blaster did the same job for 900 .
 
$5,000

:eek:

WOW...How much does a new dry ice blasting machine cost?
 
Its not just a matter of cost

On the my personal Tiger, I dry ice blasted the engine compartment, trunk, all interior, all fender wells, all under bottom of the car for $400.00. To have the complete car blasted was $1000.00. Only regret that I have, is that I did not video the entire process. Machines run $20K and up, compressor not included. One thing that I have found, is that you need to shop around, and find someone who is needing the work. Tim<><
 
Anything More Than Paint and Undercoating

I could not tell if dry ice blasting removes one of the other foreign material that many older cars suffer from - Bondo. If a person has Bondo under the old paint job, will the dry ice blasting remove it also? After all, Bondo was used extensively in body repairs before Tigers became somewhat valuable.
 
Bondo??

I personally did not encounter any bondo, so I am not qualitified to asnwer the question on the bondo. Lets hope MII, from Germany, could answer the question. I do know the Tiger that I'll be dry ice blasting, in months to come has some bondo.
 
$ 5250 to be exact, The car was apart , ie: a shell. Price included body in and out , doors hood and trunk. At 5 times the going rate I am wondering if they use Gold Dust !
The day he showed up here there was a Bently 2 Tigers and a Maybach in the shop along with the mustang , so I think he got all Pie eyed and threw out a stupid number ! Shot himself in the foot because the other cars belong to a friend who just stores them here .
 
Media Blast in NorCal

Since we're full disclosure...

I DO believe that these services judge the marque, or often 'the mark' as the case may be :eek:, in order to quote.

My phone estimate came after the business manager asked, "is that a real Tiger?".

The economist in me thinks: sq footage (size of vehicle) x amount of work to be performed by that area = price. The realist knows that; size doesn't matter as much, complexity does, but perhaps perceived value to buyer the most.

I can understand a sliding scale, and if the project were a $2M Ferrari, I would expect a higher price...but would also expect kid gloves and a most thoughtful service. Of course, we often don't get that perceived value...

My car was $3000 for mixed media in Sacto. It seems like a lot. Especially since the friend that referred me to them is a body shop guru and had his personal panel van (late 50's Chevy) taken there. I know he paid nearly half what I paid. Yes, he had his done a few years (3-ish) prior.

His job was not larger, less complex, or less involved.

BUT, I was comfortable with the shop, with a long history, positive word of mouth and in the end any misgivings were more due to my lack of communication with them v. any 'mistakes' they may have made.

The $3000 included:
- Plastic / other soft minerals wash to remove base paint and primer.
- Rough out of problem rust areas with mineral; the first step won't remove, but rather will expose rust.
- Metal jet (Zn) over small pitting to remove rust holes; hardtop touch points, driver's floor, minor lower sill.
- Hand sand to remove excess metal.
- Headers blasted and other misc bits.
- Full epoxy primer of everything, including stuff I didn't want (hood latch).

I am just starting the re-assemble phase and as stated by many, 'sand' is everywhere. One key issue I found yesterday is that because they left the tunnel insulation in place, the media spread under and will continue to emerge. But, I took the lower part off, reluctantly, yesterday and will be dynamat-ing it. Therefore, I'm pretty confident most media will be removed. the concern is spots where it will lay in wait and then absorb moisture. Inside sills, pillars, etc. Makes sense to me, but I'm hoping the epoxy spray also reached some of those areas and sealed them. I can see evidence in some locations.

I was aware of Dry Ice, but heard two 'negatives'. First, it isn't dry. Therefore, moisture contacts purely exposed metal, and the claim is oxidation / rust will begin almost immediately. I'm not too too sure of this claim... The other is less of a negative, I think... This preparation may not provide the most preferred toothy surface for over primer adhesion. Again, this one is also heresay and may be less relative depending on owners preparation plans (sanding). Sorry, I can't claim either one to be factual, just what the competitors spout out. I like the way dry ice seems less harsh, at least with regards to removal. But may take more body hand work than the media method I used. If done 'right' it all comes from somewhere.
 
Yes I do believe they quote based at least partly on the Mark of the car. Years ago I would mention Tiger and get dumb looks , now I dont dare say the T word for fear the price will jump 40-50 % . I dont do many cars anymore but over the years I have learned to quote Alan Funt ....Sometime , somewhere when you least expect it ....SAND !
 
RENT

I noticed on the Coldjet site they say you can rent a blaster. That might bring the cost down to something affordable.
