* I polyurethaned/painted my 4x8 at both extremes of the weather, at least for N.Texas...not Panhandle-type weather (it actually snows up there!). I used oil-based Min-Wax poly, mixed with thinner for my base coats, quickly followed with paint, at over 100 degrees in blazing sunlight, and also paint+thinner (no poly, except on the floor and along the bottom wall seams, since the exterior and both sides of the doors were already water-proofed with poly) between 80 and 45-40 degrees inside (even mixed with 25% thinner, it started to get thick below 40 degrees).
* I painted the interior in either Jan-Feb ?, using a small space
heater to warm the interior up to 80 degrees or so (so the paint would adhere, and cure). I had to paint in stages, pulling the
heater out while I was inside, and stopping the painting when the temperature dropped inside below 45-40 degrees. Then, I would re-heat until I could resume. Took me two days, over two colder weekends. I didn't mind the fumes (I used to build Military models in a small, closed room in the 50's-60's..."smells like Victory!"). But, a word of caution; don't wear your only good pair of glasses when painting a ceiling in a 4x8 trailer, only inches above your head. Dries quickly, and irremovable from plastic, coated lenses!
