Just curious as to my options on a stainless commander.    I just bead blasted it grey and it's much better than the reflective surface it used to have.   I'd like to use a bake on coating on the pistol.   Will the roughed up surface from bead blasting allow the finish to adhere to the stainless?   Any reccomended coatings?  

Glass bead peens, Oxide bead cuts,

Use oxide media to prep for coatings,
Duracoat if you want a flat mat finish, moly resin is you want to bake and have more of shiney/glass like finish (even over the rough oxide sub straight).

P.S. My thoughts are I buy SS pistols since they don't need a coating for protection.  Buffing wheel for polished surfaces, glass beaded for that softer sheen (step down from 220 Plus for more of a french grey), or just 120 oxide for the flat mat non-reflective finish.  The best part, 2 minutes back in the blast cabnet and there good as new.

Actually I only bought stainless to help a family member out that needed to move this particular pistol.   I prefer my guns be black.  Now this one is at least a dark grey, close but still not what I was looking for.   How hard is it to remove a baked on coating if I dont like it?

It's easy in a blast cabinet to remove.
