I try not to buff anything in the direct sun, but I am sure they will be ok. You might just have to mist the pad with water if you do have a problem.
I was a big time 3m and megs freak back in the day cause that's what everyone else used. I went in a store back 10 years ago and tried to buy some 3m, but they did not have any. So my friend worked at the store told me to try the presta 1500 and I was more than impressed and have not looked back. I am not saying that 3m stuff is bad, I just found something that works faster and safer with an end result that was amazing. 3m just seemed to marr a lot and it was a flat shine.
I love thick clean gloss with a reflection you can see for a mile. When I had a mustang years ago I use to take it to car shows, everyone use to ask me what wax I had on it, and I use to tell them Mothers (back when I use to use it). They would think I was lying and some would even argue with me and tell me it must be a repaint, until I showed them every jam on the car. I would tell them it was all prep, wetsand, compound, polish ( I would never tell anyone what I used back then) and some were just amazed! I then use to land detail jobs left and right.
I Love autopia and everyone here, so I want to share this stuff with all! Even with 15 years experience, I still learned quite a bit here in new products and the pc (the tool I always dreamed of)
