It was the first time I've used it for an entire model. It had a seal cote of Future, so it didn't affect the paint at all. It worked very well on the top where it was Model Master gloss gull gray enamel and 2 cotes of Future. I put the panel line accent on, let it dry and wiped the surface with mineral spirits. In the bottom I didn't get quite so good results. I had used Testors square bottle flat enamel paint and it took quite a few cotes of Future to gloss it up enough for decals, and the panel line accent didn't flow into the panel lines as well and some came off with the mineral spirits. Next time I will use less Future. It's always a learning experience.
