Phil I have a Q for you. I noticed today - that on my last wax job I still have some dried white wax in the seam where the rear spoiler meets the trunk top part. You can only see the dried wax when you are looking at the rear spoiler from the front of the car.
What is teh best way to remove this hardened wax? I tired a micro fiber towel and an old credit car. It is really in there!!
