i tinted my own windows and no one ever noticed it was done by me, its a***** on curved windows took me the second time to get the back on right , the back side ones are easy tho, make sure you have a blow dryer, soapy water and a squigy, also for the curved window you will have to put the tint film on the window from the outside first ,make sure you dont take the clear sheet off cause it will stick, spray soapy water on the window , and then mold it to the window with the blow dryer, dont let it get too hot tho, then cut it to the size of the window, then take it off spray soapy water on the inside of the window and put the tint on, make sure you take of the clear sheet so it sticks, , now work out the soapy water from underneeth the tint with the squigy starting from the middle and working out, make sure you have it all lined up right cause if you take it off it wont stick good, get all the bubbles out. trim if you need too and your set
be carefull and patient cause it hard and frustrating if it gets messed up
hope that helps cause if done right it will look pro, thing is make sure you have good film cause some of them dont stick well or turn purple after a couple of months :thumbup:
