I got a set of weather seals (both top and bottom) from our hosts for my 109 3 Door, and I was wondering if I need to apply anything like silicone along with them. The PO appears to have used something rubbery on the bottom, but I can't tell about the top, which is where all the water is coming from. Any thoughts? Thanks.

I don't ever remember seeing any sort of sealant applied to the back side of the weatherstripping. Maybe others can comment. The problem with silicone RTV or weatherstripping adhesive is it can be messy and a real PITA to remove if you ever have to replace any pieces of weatherstripping.
If you use silicone RTV, make sure to use non-corrosive silicone made specifically for metals. Many RTV silicone sealants are 'acid cure'. For 'acid cure’ RTV, exposure of the material to atmospheric moisture initiates a catalyzed reaction of the acetoxy silane crosslinker with hydroxyl capped polydimethylsiloxane linear polymer which leads to the formation of a three-dimensional silicone polymer network and acetic acid.
