He uses Zymol products as do I, though I do not use Royale Glaze, I use the Z3 Glaze and Concours which work well for me. I noticed in the video he also used HD Cleanse (the brown stuff) whcih is only about $25.00 for 8.5 ounces and the Lehm Clay bars he used are only about $22.00 per bar.
I did notice too he used high pressure pin point rinse water and I was always told not to use high pressure!
Interesting video and nice cars...Check Zymol
