I assume the ceramic media doesn't leave any "grit" behind. There are horror stories out there on the use of various "blasting" methods and some sort of grit being left behind and not easily cleaned out of all passages/etc. BTW - very nice looking case.

Dry Ice just contains water. You don,t have to worry about grid.
Mainly they use this method of cleaing for the food industy to clean their tools. Food equipment does not allow any other cleaners. bob |

Actually, sodium bicarbonate is used on food equipment here in the US, but expensive dry compressors must be used (as opposed to oil-bath type which put an oil film in the blast air).
As a reminder, following the tumbling process, ALL the oil plugs in this case were removed and the passages thoroughly cleaned. Ollies isn't about to let a case go out the door if there's a possibility of it stroking out on startup. That said, I will thorougly clean it before assembly just to be certain.

Resurfacing this old thread because I'm about to have the same treatment done to my case. Do you think you could cerekote the case after this process or would it still need to be sand blasted to rough it up a bit for adhesion? Isn't there a clear aluminum coating for polished surfaces? I would think something like that would work to protect the case for another 20 or 30 years.

DO NOT sand blasts/media blast a case.
What are you trying to achieve? Cheers

Jeff, I have some small pits on the case. My thought was to use cerekote on it for a little protection. Is there a version of the product that doesn't require sandblasting? I thought there was a clear or something for polished surfaces for this application. I've seen this done on many motorcycle cases. Just a thought for some additional protection.

An aluminum case is worth more bare than painted. Same with transmission cases.

I get that for sure but cerekote isn't your normal paint. I would think the clear would have a real benefit to protecting the aluminum.
