Do not touch your car with armourall!!!
It will destroy any vinyl, plastic, rubber, etc.. that it touches. It eventually shrinks things, which forms cracks. It also creates a nightmare for anyone trying to repaint a car that has had armourall used on it. Silicon spray is aslo as bad.
Go to any local auto accessory shop and ask for Meguiars Natural Shine for the interior and Trim Detailer for the exterior and no i don't work for Meguiars, have just found these products to out perform and out last any other products.
Cheers,
Chris.
