I found a fairly good protectant today at Wal-Mart. It's called "Black Magic" and it comes in a pump spray (like Armorall) It's a clear liquid and contains no water like Armorall. It goes on smooth and really shines the Compass plastic good! It also has a pleasant odor. Sort of like that "new car smell".
I like it and it will replace Armorall on my detail list.
