Just go extreme and put 2.5% all the way around including half way down windshield like I did and there won't be any more worries about sun at all. As for doing it yourself it's quite easy to do just takes time and somewhere where the wind isn't blowing and a friend to help and it can look very good. Every vehicle I have owned I did the tint job on them myself and it came out looking just as good if not better than the pro job. But if you're worried about problems then I'd definately recommend getting it done pro. As for your car 35% would look pretty good and would look darker because it's a white car so the contrast cuts it down too. Have you checked to see if mirror tint is allowed there or not. If it is get mirror tint it blocks out the sun and alot of heat and doesn't cut down on the visibility from inside out as much as black tint does.
