OK, so I've replaced both side-mirror rubber base-gaskets. Both were under the original mirrors from Vintage. My car sits outside but under a carport (with side curtains) here in California. I don't want to do this again for a while and was wondering what protectors you guys use for rubber parts on our cars?
I used Armorall on several past cars and it turned some of the rubber/plastic parts white so I don't think I want to use that.
