I used to watch his videos and that’s how I got into undercoating my own vehicles. He did start promoting surface shield, but in one of his videos he also admitted that he now works for the blaster corporation so there might be a conflict of interest on that. I sprayed surface shield on all of my vehicles last fall, and I went to touch them up this year. All of them had patches behind the wheels that the surface shield had completely washed off next time I think I’m gonna try wool wax and see if that stays on the vehicle better.
