I did 2 things that made my horse trailer and its dressing room
AMAZINGLY cooler. 1.) Bought roll on tractor paint at the farm store and
painted the roof WHITE. Just used some TSP
to clean it first, primed it white and rolled it on. You have to be close to
see that it isn't a great job. 2.) PAINT ON insulation! WOW did it work! http://wwwnansulate.com/nansulate_translucent_PT.htm

is the stuff I used. I STILL can't believe how much difference it made....but
of course, your mileage may vary. Just cleaned the metal with TSP and rolled it
on! Faustina Duffy
