Bill. Thanks, There is next to nothing on this but I was hoping things might have changed in the last five years or so. Do you think a Krane heat mat that I could only get a 100F hot spot reading could do it? Is there a known temp/time that could cause it. I dont think I want to do any Post Mordom testing LOL. Think you will make the Daytona Expo this year. I'd love you to stop by my house on the way there or back if so. Vic
