i wouldnt want to mess with tryen to remove or install a windshield on my own. i would leave that up to the pros if i were you. you need special tools depending on the car. also you have to deal with that really messy glue. it has to be done proper so that way when your on the highway it doesnt end up flying off! or even having to deal with hearing that drafty wind noise!... id save the hassel and just pay a pro.
1 other major problem....LEAKS!!!
