That's looking great Groovy. Sounds like it's been a smoother ride than the first one!
Now, I'm just concurring with Simon here on temps etc. IME 20-25° C is the perfect range for application (as most manufacturers put on their labels). Humidity is also a huge factor. 50% is perfect, and I never spray over 75%.
I know I'm talking about application there, but I personally apply the same principles to curing/drying (for the most part). Warmer is not necessarily better here. You don't want to "bake" poly or lacquer like enamels, but that's a whole other kettle of fish.
