The application I most use K38 for is primer in the mold before layup. I like it cause it fills the weave really well. But spraying it with 1.8 tip is so dry today that I thought I might just ask. I've used probably two gallons of the stuff over the past 3 years or so. I have a quart of k36 here, but I have never opened it.
Next layup I will give it a shot and see the difference.
Sean,
It sounds to me like some of the solvents have evaporated from you K-38. I couple years ago i got the bright idea to re-package my K-36 into small, easy to use, PLASTIC squeeze bottles. That worked great for about the first 3 months, then the stuff started getting thicker and thicker even in the bottles that I hadn't used yet. It seems that the solvents were leaching through the plastic bottles.....Maybe that's why PPG sells the stuff in metal cans! Anyway, I found that I could resurrect most of it by adding reducer. The last of it was ONLY good for spraying in layups because it was too hard to get a smooth application when sprayed as base coat.
