Dry Ice

[TimG]

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.
