I got a pair for my F1, very happy with them, I'm fairly sure they are the same ones that DS stocks the same ones, they were out of stock so bought direct and saved a few quid too!
Use adhesion promoter of the same paint scheme you use for the primer, base coat and lacquer and you'll be fine, that's how I did my seat hump, I have another seat that I might paint as the plastic of the one I've done isn't 100% smooth, need a bit more High build primer then take a bit more time with the preparation.
I haven't painted my side panels yet as I need to get another can of promoter, they're satin black I think on the F1.
