Again, I don't want to beat a dead horse, but I have been unable to commit to the 303 protectant for the dash. As for the leather, I have not used any products yet, since the car has been stored so much indoors.
Concerns...
Vinyl & rubber - My local Lincoln dealer said that 303 is great if you constantly use it, but if you stop, the finish goes to he**. The other car dealers and detail shops (except one) have never heard of 303. The only one that did swears by it. They are also a convertible top/upholstery specialist.
The Porshe dealer said they use a cleaner then leather conditioner on their dashes. Jag had no recommendations (one even suggested Armoral

). Mercedes uses their own line, but the detailer said he used Meguires on his own cars, including older cars.
I am considering using Ford's leather/vinyl cleaner on the dash/vinyl items, Meguires leather conditioner on the seats, and something else (perhaps 303) on the gaskets.
