Soda blasting - Does someone have any experience

Okay!

The other day I had a few parts painted (spray) that needed to have there last finish.

and guess what I started with a new spray can in the same color but not the same kind of paint and the paint come off and became something...ugly ! period

My fault anyway and a Classic error.

So I have sanded the parts again and it took forever to get them finished.

So I found something that's faster and also cleaner. And they call it soda blasting.

But now I want to know if others have any experience with this soda blasting before I buy the necessary equipment for this.

I'm mostly interested in surface finish of part after the procedure. Is it damaged or not ?

Because the reseller did not know if it where possible to use with abs - And on YT they say it does not damage the underlying surface.

So hopefully there's someone who is using it and willing the share his thoughts with me.

I GLASSBEAD  MY PARTS @40 PSI AND EVEN DELICATE FEATURES STAY INTACT.

GIVES AN EVEN FINISH AFTER TAKING OFF SUPPORTS AND SANDING..
