Haha, I think every board has these type of people. One board I frequent has just that guy. He is one of the board "gearheads" and really is knowledgeable about the mechanics of the cars, but he also tries to be the knowitall when it comes to detailing. I've mentioned him before, but every wax thread he has to put in his Liquid Glass plug and how it's the best even though Gold Class is the only wax he compares it to. :wall Then a couple days ago someone posted about removing water spots, and people start sharing ideas for drying to not get them, and he chimes in with the California Water Blade. When couple of us start talking about how that isn't the best idea, he gets defensive and says he's been using it for 8 years, and to come see his car for proof that it has no scratches or swirls. I didn't post it, but I was thinking "yeah right, I can almost guarantee you have swirls".
