Craved, my custom designs are a trade secret but I can tell you the design goes on first.
You can have any darkness of tint in dyed or metal, but always go metal if your keeping your car for more than 6 months, because dyed tint is cheap rubbish, I personally never use it.
95GTST, I charge $300 for a retint in 20% and if youve taken the back out you should get a discount because it makes the job a hell of a lot easier.
Hippy, I could call my tint "Pimped Out Mother of All Zynchromian Based Carbon Fibre Hand Made By Albert Einstein Tint" and it could be the same as Frankys Tip Top Tint, names dont matter as long as its a metal based tint. If its a metal sputtered film its even better.
