I live in Florida, raised in MA though. A while ago, I was trying to figure out how to keep my horses cool, while traveling in the hot, Florida heat. While surfing for solutions, I found a website, that has insulating paint... I was skeptical, but tried it. What an amazing job it did, immediately!!! It lowered the temps in my trailer about 20 degrees from what it used to be... I couldn't believe how well it worked!!
So please, take my advice, if your looking to cool the inside of your trailer, go to, HY-TECH Insulating paint and insulating house paint additive DIY insulation solutions and look for the product called BUS KOTE. It's AMAZING!!!
