I agree with the 24 + a few, in general. Temp + humidity in my unheated 85-yr old basement, with direct access door to the outside, is "comfortable" even in winter, but I don't generally varnish until mid-afternoon to let the temps get >65 before varnishing. AM temps usually around 60 this time of year.
So - the way the clock works out is that the 24 hours + a few puts me in range of the dinner bell - and is definitely after the sun is over the Bass Ale yardarm - so I let it ride till the next morning. Its a logistics issue as much as anything.

Which of the newer stearated sandpapers do you use?
AFAIK, after 24 hours the sanding is needed to help promote adhesion.
I've never tried that paper, so no opinion. The stuff I really like is Norton 3X gold-colored 320. I like the backer paper, and the grit works well for me. An alternative would be the 3M 261U, but I like the Norton better in 320. I also have some Norton 400, but that didn't seem to add any benefit v 320, and the 320 cuts a bit faster.
I use the 3M in P600 for other situations.....especially smoothing between coats of shellac. It's really good stuff, IMO.
When I started woodworking, I didn't know squat. I have progressed in 30 years - now I do know squat.
