Based on the above test data, we are of the opinion
that the coating has excellent performance characteristics.
The material complies with the requirements of MIL-W-5044 and exceeds these in several characteristics.
300 hrs. = 1 year outdoor exposure.
1000 hrs. = 3 years and 4 months outdoor exposure.
