NSX engine Before Dry Ice Blasting, our NSX had the normal road grime for a 30-year-old car.

    1. Oh for sure! Our Project FD RX-7 was a gunk-filled mess. Now it’s so nice to work on what’s essentially a brand new car. The only downside is that you won’t want to work on another car that isn’t blasted! haha.

  1. “Once you go ice, nothing is as nice.”

    To this startlingly bit of wisdom, I can only add…’yup, yup.’

  2. Will it remove surface rust? Just typical red blemishes and such, superficial at best. This sounds like a much better way to handle undercarriage paint prep… At least in my case. I hate having to use wire brushes and such.

    1. Dry Ice Blasting is a game-changer. Check out the more detailed article on the process for Project FD RX-7. The aggressiveness will depend on the settings and experience of the technician. It can remove undercoating or it can be gentile enough to not remove it. I just blasted a lightly corroded and gummed up aluminum differential and it’s perfectly clean and ready for paint prep.

  3. Would love to know the total weight of the gunk that came off. Can we get before and after weights the next time?
