Thats just my view..I wasted loads of my pot of Bue Velvet as wehn I first got it I was waxing porbably once every other wekk.
I then accidently left it for a month or so and beading/protection was still there.
So maybe its lazyness but I found it better to have just one coat Putting 2 on does nothing more then waste products, likewise putting lots of wax on is just as wastefull and achieves nada! IMO. I used a panel pot of rubbish boys (dodo) on mine and used hardly any..and my car is a lot bigger then the Clio!
may just get a panel pot and see what its like then
