This is a well written informative bulletin. A large percentage of premature coating failures are due to salt contamination left during or after surface preparation. I believe the subject of such contamination should be addressed in depth in an additional bulletin. That would provide very important information to the industry and could assist in a reduction of such failures. Since it has been shown that air borne deposition of salts occur everywhere it would provide information needed everywhere.

While I agree you Mr. Johnson that the bulletin is informative, I do not agree with his blanket assesment that a "large" percentage of premature coating failures are due to salt contamination. Here in the midwest in the water tank coating industry, I cannot remember one failure attributed to salt contamination in my 30 plus years of performing this type of work. Now bridges would most likely be a different story for this region.
