I was browsing the optimum car care forums earlier today and I noticed there they said their Opti-Seal product cures in about 4-5 hours when someone asked about topping it with their wax, but I know on the Obsessive Detail site suggests 24 hrs. I just did my girlfriend's Corolla with OS and she's heading north for a bit leaving earlier tomorrow. However, I want to top it with some Wet Obsession before she leaves. If I were to try to top it after a few hours (5 or so) would I just be wiping the OS off the car?

In any event, that was a breeze to put on. If the finish is as good when its cured as people say, I think I have a new favorite product.

 

You will get the most durability if you let it cure for 24 hours, that is basically the full cure time.
