Does anyone here have any experience with the forster gold and silver inlay filling kits sold by midway and others? How well do they work?

I thought it may be a decent way to give my cz some character but I don't want something that is going to look like crap or possibly mess up my gun.

Really easy to use, replaced the gold on a special 1100 Rem. after it had been re-blued.

So it turned out well?
