i bought some red robin wrinkle powder off ebay from roseys powdercoating.. i love the color but i cant get it to wrinkle. the tag on the powder says its a epoxy formula and has a bake schedule of 400 degrees for 10mins or 350 for 15mins. im useing a toaster oven right now. i used black wrinkle (different company) and it did great but this one wont wrinkle. it comes out with a mostly smooth look with very little if any wrinkle at all..any advice on this type of powder…thanks
