Using the heat gun is pretty simple. I just bought a $10 one from Harbor Freight. According to the box, the high setting will reach 1125 degrees Fahrenheit. I tried the low setting (575F) and it was almost impossible to get the plastic to change. I just held it about 1/2"-1" away from the plastic and as soon as it starts to turn black, you start moving it. It is pretty amazing, it's almost like painting them. I initially used one of the propane torches that you can buy at Home depot and it worked even faster, but I was worried about things getting too hot.
As far as the paint, I didn't have a problem anywhere and I am usually the type to screw that sort of thing up. When I got close to the body, I tried to hold the gun vertical so it wasn't shooting directly at the paint. Once you see how quickly the plastic changes color, you'll realize that you probably won't harm the paint since you won't be close to it for more than a second or two.
When I looked at the flares today in direct sunlight, there were a lot of what I would describe as blotches where you could see that I wasn't consistent with the heat. Some places looked really good while others looked sort bad. Everything is black, but some places have more shine than others. I started on it in the late afternoon into early evening on a cool day (55F). If I did it again, I would do it in good light on a warm day. That would allow me to see the fenders better and I also think that they would heat more uniformly if they were already warm from sitting in the sun. I would also spend a lot more time going back over areas I had hit.
I noticed something interesting yesterday. I attempted to go over an area that I had hit with the torch and the surface would not change. I have a feeling that once the plastic completely cools and "cures", you can't smooth it out. I will try and go over mine again, but I want to wait for the 303 to wear off a little bit.
Hear are a couple of you tube videos demonstrating the technique.
Here's one on a Jeep. I went faster than this guy which is probably my problem. I also went side to side rather than lengthwise. I wish I had done it this way.

This one is going to come out really blotchy is they don't go over it again.
