I contacted Krylon to find out which clearcoat I should use to protect the camo paint I was about to apply to the extra TS stock I had just gotten from MoM. I almost didn't expect a response, but the one I got made me chuckle a bit. I will now use Krylon wherever applicable because of this. "Dear Jacob, Thank you for taking the time to contact Krylon. We appreciate your interest in our products. The Matte Finish 1311 is more for interior use. It would be best to use the Crystal Clear Flat 53530. I used it when I painted my AR a few months ago. It did not add any shine to it. I put three coats over the paint, to protect it. I hope this information is helpful. Please respond back if you require additional assistance. Regards, Craig Krylon Product Support"
