Clear Coat Questions

[guenthner0315]

So, I'm having trouble with the clear coat I'm using on my Captain America shield. Specifically where I'm laying it over pain aluminum. I'm getting a ton of white smudges forming under the clearcoat after a few days. The smudges are under the clear, and cannot be buffed out. I've attached an image that shows what I'm talking about. You have to angle the piece at a certain view to see it.

This has happened twice to the back of the shield. I've stripped the back twice and recoated and they reappear.

I clean the metal with acetone and seal with a Laquer, although I have tried an acrylic as well. I'm thinking MAYBE I'm clearcoating too soon and the acetone is leaving a residue that I'm sealing in.

I'm going to try to leave the metal dry for a couple days after cleaning with acetone. See if that helps

Anyone have any ideas?

Smudges are forming on the front of the shield now. I want to figure this out before I strip the front of the shield and start over

This usually tends to happen when the clear is not sprayed wet enough, not dried in a high temp area and then bring grabbed before cured. Or this can happen to the paint too..

I used yo do touch ups on cars at a body shop in high school. If you have anymore questions just ask.

Thanks, yeah, back then I was using a Lacquer clear, which take forever to actually cure. I was touching it too soon, causing smudges. LEsson: Learned.
