NSX front compliance clampThe front suspension’s “Compliance Clamp” is very intricate in shape and difficult to clean.

NSX front lower control armThe front lower control arm was relatively clean, but the front of the arm at the ball joint was stained and difficult to clean.

NSX rear framerailThe main frame rail just ahead of the rear tire had the most grime on the car.  The parking brake bracket bolt was almost difficult to identify.  There was also a lot of buildup on the frame itself.

    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?
