Ken- agree with you on all points. Charles- is there any way to get a paint sample and run a test? I can imagine a stepped approach of ...apply one coat, let it dry, measure SE, apply another coat, repeat...
seam treatment is a head-scratcher. there are tried and true methods for existing shield technology, but this would be something new. need a creative method to experiment and iterate into a solution.
