So nice. Love me some Opticoat. I used a similar, though not as good product (cQuartz) on my 2011 M3 and it has lasted over 2 years! Wish I'd have done the wheels...<sigh>

How'd you get the wheels so clean (the tar, etc., not the Full Effect wheel cleaner step, but the next one)? You say you 'steamed' them. Literally? With what? I see the pressure washer in one of the pics.
