Will this be done by hand or machine? How long you planning to spend on it?
Be careful using autoglym SRP as it has a lot of fillers which "hide" marks in the paint but after a few washes they wash out and the car can look very swirly/dull again.
Something like Meguiar's 205 has about the same, if not slightly more, cut and has no fillers so you will have a more true finish.
I always liked collinite 915 wax, it gives a lovely finish and great beading. Having said that I usually use Gtechniq C2v3 which sprays on and wipes off, it takes a fraction of the time compared to waxing, gives a lovely glossy finish, the beading is better and lasts longer.
