Drying MIG Jimenez Mud "splashes"

hello all, I have read all through the pamphlet that came with my Mig mud "splashes", and a how to by MIG himself, and did not spot any special instructions or requirements for drying this product, or of any need to "over-coat" it with anything else. I "flecked" some off a brush onto a bronco I just finished (sorry no pics I just dropped it off at the model car contest at the Detroit Autorama earlier today) and a full day later, everything was wet as when I flung it on there. I put the whole thing the dehydrator last night for about 12 hours, and today it was much better, but still somewhat tacky. I love the wet-look affect it creates, Im just unsure if I didn't mix it well enough, or if it's supposed to be coated over after the application. Any help or insight is greatly appreciated. 

Thanks! Rudy
