Ram Rod

If I were to paint kydex for any reason....I'd use the same thing I've used for years for automotive plastic trim color matching. Duplicolor Adhesion promoter, Duplicolor paint then Duplicolor clearcoat right out of the spray cans following the instructions. Use a prep wash and possibly rough the material up a bit with fine sandpaper if it's smooth.

Edit..(correction)...I apologize for the 'Duracoat' three times.......it's actually Duplicolor paint and products (vehicle color match paint) that I've used with extreme confidence on the vehicle plastics. A daily driver is subjected to a lot of elements to include chemicals, solvents, the spray car wash, temperature extremes, and UV radiation. The Duplicolor paints get my nomination for standing the test of all that + time. Again... I apologize for any misleading. I will now edit the word Duracoat to Duplicolor. Thanks for your understanding. Duracoat is actually a firearms finish.
