Hi all, I am going to be installing new windows and rubber gaskets on my '53 3100 five window. I have new glass and rubber from LMC truck and it will be my first time doing any glasswork. I was wondering about the following: is it common practice to use a sealant between the rubber and the cab metal, and or the rubber and the glass? or will the window seal just fine by itself? Where the rubber ends meet on the rear and corner window seals, should the ends be glued together? Where should I make the rubber ends meet, bottom? Top? On the side verticle? Thanks for any helping info.
