Epoxy: To Evaporate and Blush or not to .....

I wrote Dr. Rot twice (the original question and one follow-up) yesterday and today to ask him about using CPES on my boat. I asked him how I deal with the "Blush" of CPES and what method he recommends for coating the inside of a kayak.

I like his page, his products seem very good and he is sincere and helpful. Still his answers are a surprise. First that there is no "Blush" with CPES (he says NONE of his products have this). But most hard to figure out were his two (2) completely DIFFERENT recommendations reguarding the wait time necessary for the "Solvents" to "evaporate" BEFORE it is a good time for coating over the CPES with regular epoxy or "Clear Coat". I like him and think he is honest and knows what he talking about but I cannot understand how come his answers do not seem to "add up". Does anyone here have an opinion to help straighten me out on this???
Both of his e-mail answers came today with in 1 hour of each other:

"None of our resins blush, including CPES. That's just one of the
advantages of using our wood-derived resins."

Answer # 1 at approximatly noon:

"On your boat, CPES would form the base coating for Clear Coat. You would apply one coating of CPES, allowing the wood to absorb all that it will, wait for a few days (or longer) so it can gas-off the carrier solvents, and then come back and apply the Clear Coat. The Epoxy in Clear Coat will bond strongly with the CPES-treated wood."

Answer # 2 only ONE HOUR later:

"So, you apply the CPES, wait until it has gassed-off the carrier solvents (2-3 hours) and you are free to then apply the Clear Coat. Basically, once the CPES-treated surface is "tacky", you can apply
final coatings. The resin itself doesn't have to completely cure, since all
epoxy resins cure in the absence of air."
