I would reccomend a pannel pot of DODO Supernatural (around £15), You should be able to wax the car 2-3 times to see if you like it. Its good stuff.
When buying DODO wax i just follow there guidelines, They have light colour waxes for light paint, And darker waxes for the darker paint.
Supernatural in a plastic tub is much cheaper than the wooden tub, So for me just wanting the wax id get the plastic!
476 Is a great winter wax, But DODO Supernatural is excellent for summer imo.
If you didn't want to spend the £60 odd for a plastic tub of Supernatural, Get one of there light normal waxes,
or wait for another recommendation.
