Remember when I posted I was having an issue with a past Ranger key custom? Well, I feel I can now say the issue was caused by the top coat I was trying to apply. I had a second thing with the same chrome paint, and it fell to the same problem, in that the chrome lost a ton of its brilliance after the application. Now, I know that some of these glossy paints warn that a top coat will dull the color, but this looked like the color was fading off entirely, not just getting dull. At least it didn't end up sticky. My guess regarding that issue was because of the low amount of spray that was left in the last can (oh right, forgot to mention that it was a new can I got for this).
Still need to find an alternative to fixing the paint in place. My Lauren key used some thinned-out school glue for the skirt. Looked dull in the end. I also thought of using super glue instead. That does give a glossy look, but I'm not sure how it handles acrylics. Going to have to test that soon.
If anyone has any more ideas, I'd like to know.
