Yeah, Pinnacle and red is one of those synergistic marriages!
You've actually found some pretty good stuff to use. Although I'm a Meguiar's fanatic, the Menzernas are my favorite polishes, especially the FP which ALWAYS gives me the result I'm looking for. I will suggest that Meguiar's #26 Hi Tech Yellow Wax is another, much less expensive way to get that nice dark glow from red, and it will last longer than Souveran. But I'm a Souveran junkie too.
Otherwise, not knowing your skill level or how long you've been at this, concentrate on the basics, which is really just avoiding introducing swirls etc, and the products become the last little bit, just gravy.
