Dry Ice

[Gasrat]

Hello, I have a 78 Camaro that has under 20,000 original miles. The car is 99% original. The dealership undercoated it when it was new. My question is what are the positive and negatives of getting it dry iced? Are there deductions for this in Vintage Certification? Thank you for any input.

My understanding is that the dealer added undercoating will hamper the certification for maximum points. I have considered dry ice to remove the 10lbs of black rock on my car, but it’s pricey due to the time it takes to remove the dealer goo. For Vintage certification, the juice is worth the squeeze. There are several videos on YouTube as well.

I am struggling with the same thing on my 57. Dealer applied undercoat.
In 57, if you opted for dealer applied undercoat, they likely shot the bottom side of the hood as well as the undercarriage.... of course, mine got it under the hood. It is so heavy, that I have to use a prop stick to keep the hood up.

Stuff is really ugly.

Tracker1 just had a 78 Trans Am done and the car looked new underneath afterwards

This is a tough question. My 12,000 mile '67 Chevelle SS achieved Vintage Cert Time Capsule in 2021 with dealer applied undercoat having small patches that peeled off to expose factory finishes. At that time Steve and Chris both felt better to leave it alone.

But, that is about the time that Gary Riley was bringing state of the art dry ice to the field. There have been some cars presented for Certification that Gary has done, along some done by someone in the Chicago suburbs?, with fantastic results.

Commercial ice blasting is done everywhere, BUT, I would not trust it to anyone lacking extensive vintage vehicle experience. You don't want to lose the FACTORY undercoat and any inspection marks etc. in the process.

Ice blasting is a game changer, maybe Steve will chime in with some thoughts. Sorry for rambling on but I have been considering blasting for another Chevelle.

In the right hands, the process could bring your 67 to a whole different level

I have seen a 5,000 mile '72 corvette that was undercoated by the dealer ruined by ice blasting. Everything was removed because the ice blaster went too far. You need one of the expensive ice blasting machines to remove heavy undercoating and a technician that really knows what he is doing. I have seen good results with ice blasting on friends cars where grease, grime and rust are involved.

I have a 17,000 mile '70 Corvette that was heavily undercoated by the dealer and I bit the bullet last August and took 30 hours with a heat gun and had good results in my own garage. It was a miserable process with a heat gun on 95-degree days in the wheel wells of the car, but the car deserved it. The reason I did it myself is I didn't want to lose control of the process and let an ice blaster do the job and come back to a bare metal chassis. Ice blasters do not want the customer near the process when it is going on for obvious safety reasons.

Same here with my '67 Corvette twelve years ago. Miserable job but no other options at that time.

The car I was thinking about doing is not a high value car but it is a 15,000 mile 1978 Camaro Z/28. It is absolutely a 100 percent survivor. Nothing has ever been touched on the car. I am talking to the guy at Dry Ice Autos in Chicago. He has done a lot of big dollar import cars as well as muscle cars. He does adjust dry ice/pressures for particular areas
Of the car.i would love to have the car done because I know the car is super preserved underneath but that doesn’t come without reservations. Thanks to all for your input.
