Honda's Shin-Etsu silicone grease for window tracks, rubber seals, etc, is top tier. I've used it on my Lexus (my other car) for years. As good or possibly even better than 303.

Lemon Pledge is ideal for this.

Not sure about that. It was formulated for wood, not rubber.
Ingredients of Pledge:
Naphtha, petroleum, light alkylate 5%-10%
Polydimethylsiloxanes (Silicon oil) 5%-10%
Water 70%-85%
You decide.

I used dielectric grease on my car and it made the rubber dry but kinda sticky. The Windows didn't want to roll all the way up for a week.

Main difference between regular 303 protectant and 303 "rubber seal protectant" is probably just the label. I've used the regular old 303 protectant on pretty much all plastic, rubber, vinyl, dash with good results. Including Marine applications on boats.
