Suntek is manufactured by CP Films along with Llumar. Llumar is the premier brand from CP Films. I think the shop I work at used Suntek when it first started, but dropped it before I got there. I am not sure if Suntek makes a metallic or ceramic film, but It wouldn't make sense if they didn't. I guess you couldn't go wrong if the film warranties against turning purple and bubbling... I am not sure if you can get a film that protects against fading... Even Llumar doesn't with their ATR or CTX films... though I haven't seen ATR fade on cars that come back to our shop after like five to ten years. I think Formula One might protect against fading... Good luck getting that stuff though heheh.
Oh, I just remembered that I think Suntek would stamp their logo on the clear liner that you peal off. It would have been a little 1"x1" black stamp that just said "Suntek" on it... I don't know how long they did that for though. Funny enough, We would occasionally pull a car in that was tinted down the street earlier that day and have to "fix stuff". And sometimes a reverse image of "Suntek" would still be on the tint because it came off the liner (the stamp didn't have time to dry in the manufacturing process).
