Actually, I sorda disagree. I haven't messed with a honda windshield but I've replaced 2 of my windshields from a 75' Porsche 914 and they were a breeze. You just need a cutting tool designed for the windshield, it is like a "L" shaped razor that allows you to cut the seal between the windshield and the frame. You just need to be careful when you put the new one back on that you have lots of hands and that you completely take out the old seal as well as put the new one in correctly and apply pressure carefully when sealing it !!!
But, its like hella cheap for windshield replacement, call around, its something like $110 for them to bring out a new windshield and install it !!!
Or just take your old one out and see how hard it really is, if it cracks, then call up the window man and he'll be out in a jiffy !!!
