I recently ordered an aerosol can of KG Gunkote from Brownell's to refinish a Glock 29 slide that had been polished before I bought it.  Is it necessary to blast the tennifer treated slide prior to spraying it?  Thanks for any help.

I have asked the same question in another listing (before this forum), and the response I got was that KGing on top of the slick black finish is not as durable as koting onto bare metal.  Sort of like powder coating on to glass.

The thing I am unsure about is the fact that the previous owner had polished all of the black finish off the slide.  It is sort of like a nickel looking finish on it now.

Is it slick and waxy to the touch (like the original black finish)?  If not, go for it.  But if you're going to coat it, why not with something more unique such as tan, OD, foliage green, etc....  Or maybe mask off a pin stripe downthe side for some character.  Sandblasting the surface is best, but at the very least, dull the surface with some sandpaper so that the koating has something to "bite" into.

Yes, it is a bit slippery on the surface.  Any idea if sandpaper would harm the Tennifer finish?

You really want to sandblast it, not sandpaper it.  You can always take it to an automotive shop and have them hit it real quick.  Just make sure its sand, and not bead blasting.  The Norrells website has good info on sandblasting pressures and grit.
