“I bought a 20x8 shipping container to use as a shop along with an existing 12x8 barn-style storage shed in my backyard. The 5-gallon pail of your product was plenty to do two coats on each structure with maybe a gallon or so leftover. My painter simply followed product directions and we've already noticed a big difference in the indoor heat level. Keep in mind we're talking South Texas, near the coast, in mid-July. Most days are 105-109 with the heat index, so a 10-15 degree drop in temperature is a welcome relief. I would definitely recommend Gardner Sta-Kool. It is the right stuff at the right time and right price!”
