I tested it on these 3d printed wheels. The pictures don't show the true shine. I used the bottle's brush for all 3. The one on the left has the clear coat or varnish applied. The one on the right has a smudge from where I touched it a couple of hours after it was painted. The clear did dull the shine a bit, but I think it looks OK for a hubcap. I'll try Alclad clear and see what that looks like. So far I'm happy with this stuff.
