Hook, are your yellow stripes make of ulwracote, or are they sticky trim stripes ? From what I've read here so far, I don't understand how your stripes are sticking if they are ultra cote. When I put ultra cote over ultracote, I made many holes, maybe 1 inch apart or less, and still had many bubbles on low heat. Maybe I just dont have the touch, I think I'll switch to monocote next time.
