clearcap sandblasted ?
What would you get if you clear capped a sandblasted section of a blank? Would you get a sandblasted look under a shiney surface or would it look like a ground edge that didn't smooth out or would you lose the sandblasting effect totally?

It depends if you use sillicon carbide or not...
You can see the other thread talking about the firepolishing results, but the gyst of it is that with silicon carbide (SiC), you have a very good chance (>>50%) of seeing a hazy layer due to trapped bubbles. This does not appear to happen with Aluminum Oxide (Al2O3) where you get a nice smooth sealed surface with no evidence of the sandblasted effect.

All of what Tony said Ann.
I use 180 grit AlOx, it works very well.
I spend a lot of time after blasting, carefully scrubbing the surface under running water to remove any residual abrasive.
