It never comes out right. Prep is everything and even the most well done niteshades tail lights and headlights still look like crap when compared to using car paint. Niteshade always has a hint of blue/purple. Most people are looking to black them out. Ive seen GPs and couple friends of ours us it and it looks a little tacky IMO. A few members here including myself had them painted and looked flawless and still allowed enough light. Voytecs car has one to many coats on it but when he hits the brakes it shines through perfectly.
