Gamera:
It's been a long time since I've used it but I seem to remember the buffing being much shiner than the non-buffing (which always seemed to me to pretty much silver paint). I really liked the Metalizer and it worked very well but gave up on it when if you so much as give it a dirty look it would peel up on me. Masking must be done with really low tack stuff like Post-It notes.
I was inspired by the Metallic finishing article in the January issue. The author used Alcad II but my local hobby shop doesn't carry it, so I'd have to order it online. Is Alcad really worth it? The stuff costs more than twice what MM does per bottle.
