Hi Jim;

My experience has shown no discernable yellowing issues with Dullcote; however, I can't say the same for Testors Glosscote. I have an Estes Cherokee D here built some years ago, and it presents a tinge when placed beside something freshly painted white.

For gloss coats I like to use Rustoleum Crystal Clear; I've seen no yellowing on the models I've sprayed with it. But Crystal Clear is a bit on the hot side and doesn't always play nice with certain waterslide decals. As always, test first.
