I'm considering to remove my windshield by myself, so I can prep it and repare any possible rust damage. Another big reason for this adventure is that this particular 245 of mine does not have that cute plastic clip you can clip your parking stickers (or whatever). The last owner got rid of it when He replaced the windshield. I just have to have it. I did all the readings concerning windshield replacement. The question is: what kind of knife do I need to cut the old one out? What brand, where can you get it? Thanks. Erwin
