I have a BLACK 2006 Acura TL and Im debating on what to use for my LSP. I just received my bottle of OS in the mail and I have some Souveran laying around in the garage. How do guys think this combo will look on Black? What about durability?
Make sure the paint is clean and free of any protection. Then apply a coat of Opti-Seal and then a coat of Souveran. I've heard that Souveran's durability is quite limited so use the Souveran as your LSP and just keep applying a new coat after every car wash or something.
Chances are, it will look good if the paint is prepped properly.
You might want to wait a day before trying the Souveran over the Opti-Seal. You might find you are happy with just the OS. (I am)
You also might try doing one panel with the Souveran over the Opti-Seal to see if it truly does add anything to the look.
