I just did a full detail on the VX a couple weeks ago. I took a couple hours every night in the garage during the week to do a bit at a time.
Used a few products from Zymol.

I have used their products for years and swear by them. VERY easy to work with and the final product is a showroom shine vehicle. This weekend, the WReX gets attention.
