Looks like you've got it. Instead of drying, I use the microwave! About
three minutes should do the trick (on high). Make sure the image is up
(place on a piece of paper towel to absorb ther excess. Make sure your
mylar is as thin as you can get, about 1 mil or less. I found a great
source for thin mylar: For some reason guys that fly these radio
controlled airplanes use extra-thin mylar
(.0008) on their airplanes (to protect the paint, I guess.).
