Yeah. The point being that there's no reason to use the LS. It doesn't add anything. I may have misunderstood what you meant when you wrote "just about the same"; I read that as "almost as good".
I'll be up front about it, I'm not a big fan of LS. My belief is that there are dozens of products out there that look as good as or better than LS for less money. Over the last few years I've purchased LS several times, every time the formula has changed. It's an OK liquid wax. Stuf is better. #26 liquid is better. 4 Star UPP is better. NXT is better. MPPP is better. Those are just off the top of my head. I appreciate that opinions will differ from mine, but that is mine.
Speaking in reference to the direct question of the combo looking better than PS alone, it doesn't. It looks no different than PS alone, so why spend the $$ for the LS? You're not putting a beauty product over a protection product, you're putting it over a beauty product that's not as good, so why bother?
OTOH, if your experience is that I'm dead wrong and it works for you, stick to your conviction. I wouldn't want it any other way; do what makes the car look best to you. There's plenty of ways to arrive at the goal, and each car and each goal is different. Have fun!
