oooouch, pricey isn't the word for it.....that's sorta expensive.
I just started using this stuff....it really rocks. It's more like a plastic conditioner than a cheap watery coating. Has the consistency of hand lotion.
The black plastic MINI parts have a very nice sheen to them and it lasts for up to 3-4 washings too.
I got if from a MINI repair shop in Worcester, MA -

Took this photo of my MINI the other day, it has been over two weeks since application and three washings so far.....
