I have to give Dr. Google credit here. I’ve been trying to find a good glass tint spray for a vintage Amber look. A lot of people use Krylon “stained glass” but then I saw the yellow Duplicolor “metal cast” which gives a very “JDM” or “euro” yellow look. When I found the yellow stuff on Amazon, I also saw other colors. I figured a bit of the orange in between two coats of yellow would look pretty aged, and I was correct. So, scuff up your glass with a little 600 and apply two very thin coats of yellow, then a lite coat of orange, followed by another thin coat of yellow. Clear the final product.
