After reading all the posts it appears that the bad MK is not color specific. Some silver, white, pearl, etc. are bad and some are good. I know the bad roll I have is the quality grade white. I had a roll of purple and it was the nicest I have had. The stuff would go on and shrink and look like glass when completed and to top it all of the stuff could set for months and look just like the day it was put on!

If it is like everything else, companies cut back to almost nothing as far as quality now so we are certainly to get less adhesive because adhesives cost the supplier and they will cut corners at every turn. Not long ago a fellow flyer had maidened a plane with MK and the stuff just started rolling off the airframe and yet it looked so well done. Once he investigated none of the glue was holding to anything.

Happy covering [8D]
