Is it worth my time to put Natty Blue on top of Meg#16. I just put Meg #16 on my black paint last week. My friend gave me 2 Natty Blue (payment for me detail his car). I want to see how Natty shine but I don't want to take #16 off yet. Is it make a different or waste my time and Natty to put Natty Blue on top of #16.
