I know you asked Harry, but couldn't refuse responding. I think the Spaz is WAY better than the Alclad. I use Tamiya gloss black spray, let it dry for a half hour, then spray on the Spaz. I hold the can 12 inches away, and dust it on. You may feel like it will dry-spray, but it wont. I do one more dusting the same way, and it looks great. On rare occasion, my gloss black didn't seem glossy enough, I added a coat of Tamiya gloss clear, and then the Spaz -it looked just as good. I've never had to polish or rub it out.
