Fact-check me on sandblasting, would you?

I have the same pressure blaster as you OP. She is a bad mother trucker lol... And I have 2 blasting cabinets. No, i'm not entitled, it just worked out this way lol...

The cabinet can do what the pressure blaster does. No way, no how. And yes I always remove most grease and grime. I also reclaim and sift from time to time. One cabinet has oxide. The other has Black Beauty.

As for paint surface compromise, I have never seen that problem. As said easy off, a trip to a car wash, whatever you do to remove the crap so it won't muck up your cabinet is an evil reality to having a Cabinet lol...
