Re: Honda Shin-Etsu Silicone Grease
I attempt to treat all of our NSX's rubber seals once per year with Shin-Etsu silicone. It can be quite time-consuming as there is a lot of rubber, especially in/around the doors/Targa.
What I usually do is treat one segment at a time... i.e. the trunk area; the front hood area; the passenger compartment area. I try to open the portion of the NSX I intend to treat up to the sun to warm the rubber (after gently cleaning the rubber first). Then apply Shin-Etsu by hand and let it "bake" under the sun for a couple of hours. Then let it cool, and again run hand/fingers over it to "rub in" and distribute the silicone evenly.
Even though the NSX resides in a garage, the rubber always seems thirsty and feels relieved to be treated. Plus, if you show your NSX, it looks fantastic!
