Dry Ice Blasting - Description & Pictures
|Every owner of an old- or youngtimer has probably heard the term “dry-ice blasting” in conjunction with working on these cars.
But why has dry-ice blasting been on the tip of everyone’s tongue for the last few years? This is a good question, and easy to answer if you know the excellent reasons to use it.
|As a garage specializing in vehicle restorations, we rely on the facts and not on assumptions when it comes to rust, especially on underbodies. Dry-ice blasting is one of the central techniques used for this purpose in our shop. This technique is indispensable, and it is our opinion that a truly professional restoration is not possible without dry-ice blasting, at least not on a professional level.
After dry-ice blasting, it is easy to see the “naked truth" on the vehicle and then evaluate the condition. Because the area blasted is completely exposed down to the sheet metal, the problem can be identified precisely, and the work strategy can be determined. If the sheet metal is in good condition or only small rust repairs are needed, then the dry-ice blasting creates a complete subsurface for adhesion, which is essential for possible overhaul or resealing.
Older techniques for removing the old undercoating, like working with an open flame and scraper, scraping it off, or using a wire brush drill attachment are completely inappropriate from today’s perspective because they are very time-consuming, tiring, and can even be counter-productive with the potential to cause damage.
