SRP is a decent enough product if you're doing it by hand, but once the paintwork is looking as good as you want it to, seal it then wax it.
Seal it with Carlack 68 sealant, then wax it with Collinite 476s. A real heavy duty wax.
Couple of coats of each of those and you shouldn't have to touch it again for 12 months, just top it up with a half decent QD.
