Whats the best way to protect the weather stripping and T-top seals?
The best way to keep the rubber weather stripping in good condition is to use a silicone spray (or gel in a tube). Open the doors, hatch/trunk, and t-tops, and let the car sit in the sun for a little while. The heat will expand the rubber and make it more porous allowing it to absorb more. It’s also best to clean the rubber with soap and water before beginning. Any dirt will prevent absorption and can cause cracking. Spray (or squeeze) a liberal amount of silicone on a clean rag and rub it into all pieces of the weather stripping. Put on a second coat if it looks like the first is being absorbed quickly. Then leave the doors, hatch/trunk, and t-tops open for a while, allowing the silicone to be completely absorbed. You should do this at least once a year, if not twice.
