Makes finishing model airplanes in a humid environment much more enjoyable. Blushing can be frustrating, and this fixes that. Great product.

Retarder is used to prevent dope blushing on humid days, but it is also great to slow drying down on hot days. I used 25% with the color dope and found my wet edge lasted long enough to completely paint a fuselage and my wet edge remained as I progressed from one side to the other with no overspray showing anywhere! Just added a new trick to my book of painting tricks! JJ Sinclair

Works to eliminate blushing in high humidity conditions. Also increases gloss and leveling.

I was having blushing in the color coats and clear coats. I added an ounce of retarder to the clear and the blushing is gone. South Louisiana is very humid in the summer.

great
