I can try. my wife is becoming an expert at getting stuff online, maybe she can find it for me. (hmmm, wonder if she'd consider getting me a new wood board for Christmas?)
Here's the Amazon link. I don't know if you can use it if you're in China.

I never would have thought of using that stuff on plastic, but those Drueke pieces do look good. I have a set like that, they could sure use the wax treatment. <sigh> Add to my list of things to get/get done when I next visit Canada.
(wonder if I can something like that here? I'll have to search for it)
VL, I was astonished at how well the wax spiffed up those pieces. Can you mail order it there? I bought mine at Amazon.
