Ya gotta wonder if the stuff is meant for boats kept in a marine environment.
The way I read it, I can only apply between the hours of 9-10 AM under a light cloud cover in 72 degree weather with a RH of less than 50% and the wood has to be properly prepared and prep'd with their pre-treatment.
Of course for drying conditions, there should be no direct sunlight, and no chance of increasing humidity, and definitely no morning dew... and over 24 hours to dry hard... but you need to apply at least 4 coats within 3 days.
Other than that... No Problemo mon!
