I am in the process of replacing the windshield weatherstrip on my 57. Upon disassembly, I noticed that there is either a beige colored sealant and/or black caulking everywhere. Where do I need to apply the sealer, and what kind should I use? I also had to order an 'end spacer kit'. Is there a proper way to adjust the windshield using the spacers? Paragon lists a 'filler strip'(#4812) made out of foam rubber. I am not sure what it is for, but I ordered it anyways. Any advice would be appreciated. Thanks in advance!
