It’s a sandblaster that uses a slurry mix of water and fine aggregate. So whatever you blast stays cool… no warpage, and it doesn’t abrade the surface as much so dimensionally nothing really changes. I’m not sure what grit the abrasive is that they use.Pardon my ignorance Bob but what is a vapor blaster?

I’ve used a similar machine at a friend’s chrome shop before. I love these machines, but they are quite expensive. $5000-$10,000 is not uncommon.
