While the toxicity of many of the best coatings can be a problem their
physical properties and longevity are a real plus. The toxicity problem can
be met with proper precautions. I have coated a number of boats with UA-75
one of the most nasty materials and by using a fresh air breathing
apparatus, proper clothing, gloves and some common sense I don't detect any
of the fumes. The time to coat a boat including setup time is about an
hour.
It does take some additional precautions but the results are worth it.
