Well, I live west of Houston and I washed it out in the sun and then pulled it under the carport to do the waxin'. It's still hot under there though with no cross breeze but I don't think it's too hot to wax it. The surface temperature of the sheetmetal isn't too bad. I had to do it though because of our "lovebug" season that's just now over. I had a billion of 'em all over and washing it just doesn't do it. I used a not so agressive cleaner wax so there was a LOT of elbow grease involved. Next time it's so bugged up I'm going to use something a little more aggresive or try the clay bar routine. Thanks for all the input. I'm going to look into those brake pads too....
