Altec- You already have it looking mighty good :xyxthumbs
The MP#3 is a very mild polish, so if you have the finish truly marring free it'll leave a pretty good gloss. You can probably get it a bit better by using something like 1Z Metallic Polish (that even improved a marring-free finish that I'd previously used Menzerna FP on!) or the Menzerna/Blackfire finishing polishes for scratch-resistant clears.
FWIW, I could never get just the look I wanted with BOS. I know Richard talks up how well it works/looks/etc. but it simply doesn't get it for me and I used it long enough to form a proper opinion of it. Noting that most all differences in LSPs are hair-splitting semi-BS, I do think that some products (UPP and Souveran come to mind) would look noticeably better than the BOS..*I* sure saw an improvement.
