I guess you are in the right track. Washing is the fundermental part of maintenance, don't underestimate its power.
I would add a clay bar in your kit, as well as the ONR that DI sell as a clay lube. So your routine can be, wash, clay and LSP.
you can pm Fminus, his working has been absolutely stunning, as well as the products he uses......
