Dry Ice Blasting in the San Francisco Bay Area

[Renn937]

Do any San Francisco Bay Area locals have experience with a dry ice detail shop in the area?

https://www.r20motorsports.com/ in the LA area seems to be well versed, but is too far to justify using them.

https://www.cryoblastsf.com/ and https://theblastinglab.com/ show up in a local search so thought I’d see if there were any testimonials or alternate recommendations.

This is not a concours car. There is just 30+ years of underbody and engine grime to clean up. Should make servicing the car less of a pain. I know there are cheaper and more time-consuming options, but I want a one and done.
