The Dodo Born Slippy is just a clay lube isnt it?
Ditch that and just use the Megs Quick Detailer instead, dont forget a spray bottle for it, this dillutes down so you will end up with 2 US Gallons worth for your money.
I also wouldnt bother with the fancy wax, as IMO you cant tell the difference really.
Just get some Colly 476 or a sealant instead for less than half the price.
