I don't wear pro-longwear alone, but I wear them everyday.
I use a similar color to the lip color that I'm going to wear, put it on and then add my lip color before the longwear dries, it extends my lipcolor for hours without being the dryness that some experience with longwear alone. If I need to, I will add more of the lipcolor after the base app has dried to make sure the color I want is what I am seeing, but usually it's not necessary.
