Wife and I put all the decals on in about a half hour. After an uncertain start, it went real fast, especially the smaller ones. I used 1/2 cap of detergent in about 16 oz. of distilled water in a sprayer bottle. I washed and dried the area on the car where I was going to put the decals. We then sprayed one sticker and applied and positioned it. I used a 5" rubber squeegee to get the water out and smooth the decal. I wiped excess water from around the decals with a soft rag. After an overnight dry, I tested the adhesion with a 100 mph trip down I-95. None of the decals came off. Everyone who has seen the car says they love the new look. I think it looks great, too. Interesting side note, the next day after the test drive, I removed the windshield to tend to a minor problem, and the car looked unreal, just smokin. I usually have a car or two challenge me when I go for a ride. With these, I had NO challengers at all. Nobody seemed to want to tangle with me. The car just looks like a full blown racing machine that somehow wandered away from the race track.
