David, Thank you for the mediation. Given the rapid changes occurring in the electronics industry matching coatings to the correct application for a given use environment has become a daunting complex challenge. It's significance can not be over estimated or ignored. David A. Douthit Manager LoCan LLC David D. Hillman wrote: >Hi Gang! I'll take a swipe at finding the middle ground on this one!
