The Krylon is great stuff. But to get it right without the oven or hair dryer which I've never tried personally, you got to do it in the direct sunlight with at least a 80 degree day. Let it sit in the sun and get super hot to the touch and then spray it very evan. Too much or too little one place or the other will cause the wrinkle effect to be different than the rest of the part. Follow those simple instructions and you won't be able to tell the difference from an orignal job. Its that good.
