I have been working on the rubber door seals. My idea of gluing the rubber seal to one sided adhesive tape, which was supplied with the seals from TAF, failed rather well. So, plan "C ' was to purchase double sided tape from the local auto spares store. This has worked reasonable well, the advantages are, no messy glue, easier to install, easier to replace if seal gets damaged or not sealing. This is also the method the factory use in the build manual for the Sling4 doors.
