+1. Not necessarily with those products although good. There's a lot of hype about detailing but if you're happy with how it is now a good wax and sealer combo will keep even the notoriously bad red colour from going dusky pink again.
Looks good, but if you did all that by hand, a machine polish by someone who is careful and knows what they are doing, is a better base for waxing. Have just done my white 92 wagon by hand and that was hard work, made worse by it being very difficult to see how things are improving. It did go from matt to gloss so that was worthwhile!
