yuk, armorall sucks.
on the plastic panels i use Prima Nero (dries matte) and Griot's Interior Cleaner for the carpeting and seats if i ever get stains.
you can get prima products through amazon or
www.detailersparadise.com
Griot's products from
Car Care, Detail Supplies, Garage Organization, Car Accessories - Griot's Garage 800-345-5789
if you have leather in the car, definitely try their LeatherCare Spray.
thing cleans and dries matte. very nice product. i use it on my G's seats all the time.
