Dan,
Everything you said is true about the curing. I've had many discussions with Frank Manning and Kent Smith, (both are friends) over the years and I take precautions to prevent such mishaps.......I also do extensive testing of my own to verify (under my controlled conditions, in MY shop here in CT). In the past, when I was using pine and urethane coatings, I sent actual sample panels to trusted friends in the biz from Canada to FL, CA, TX, OR and in the Tetons at 5,000ft (can you say UV City?) for them to test for me in their own unique enviornments. Name me another nut that would do the same?
I used a lot of 15lb before switching to 20lb. I switched to the 20 for the same reason you use 30.....fewer coatings required (in my case primer and sanding). BTW, the "holding better detail" line you hear is a function of the craftsman and the condition of his tools.....not the weight of the material. The 30lb is not practicle for me.....harder material = more chips which = more time. No savings there for my personal situation.
For anyone following this thread, what Dan is saying is there is a HUGE difference between dry to the touch and curing.....REALLY BIG! Acrylic latex will take up to a month to cure......enamels, 7-10 days.
