We just redid ours with Henry's Tropic Cool. It is supposedly the best there is for hot weather endurance. I did quite a bit of research before deciding on this and felt it was the best. You can buy it at Home Depot. I paid $330.00 for a 5 gal bucket. Our 5th is 33 ft. and i was able to do two coats with the 5 gal. This is supposedly life time guarantee. It's easy to apply with a roller. We did around the vents and the edges with a paint brush. If you use this make sure you mix it well before applying and mix again between coats. Our 5ver stays in AZ for the summer so we selected something that will withstand the sun and heat. With washing the roof down and putting the coating on it only took my wife and i about 3 hours total.
