Is it worth it to do it on my own with a "ebay" kit for the 2 front windows or pay a few bucks more and have the pros do it? Also what % would match the rest of the truck (stock). 20% ?

 

some times it is better and cheaper for a shop to do it. It then will have a worrinty.

 

Pay someone to do it. How many times have you seen a screwed up job by some do it yourselfer? It's worth it to pay the experts. I found a company to do mine for $25 a window. Check your state laws and see what tint is legal. If you get the front to match the rear, it's probably going to be too dark and illegal.
