Oh boy, just got done (for now) applying my tail light overlays with the cut outs. The first one I had a lot of trouble with till I realized how pliable the vinyl really is once heated up. I did a lot better on the second tail light. I've never worked with vinyl before but I'll say as long as you are a patient person or like in my case, can encourage yourself to be patient for the sake of your car, you should be able to handle it. I can't imagine doing it without a heat gun or a professional hair dryer. My personal advice....
1. Clean the light first (soap/water mix)
2. Buff clean, make sure there's no finger prints
3. Spray some soap/water mix onto the light and onto the vinyl overlay
4. Using a squeegee of some sort smooth out the face of the light as much as possible. Get out all of the water too.
5. Start working on the edges, I choose the huge PITA curves at the end of the tail light (outside edge of the car) to start with. Heat the vinyl up to stretch it and then firmly press it down/squeegee it flat. Don't try to do the entire curve at once unless you're already experienced. Work from the inside out, saving the edges of the light for last. To avoid creases/wrinkles you're really gonna have to heat/stretch the vinyl.
As far as the sale, thanks Andy! got them in a week flat. They were shipped to my work and my secretary was trying to figure out if the envelope said "F$*# me" or "kill me"...turns out it said "Fragile"
I'm gonna see if I can fix up the first one tomorrow morning and I'll try to get some pictures too.
