Very familiar with the Junkman and I met him in person a while back (I think it was at a Meguiars event but I can't remember). He's also a member on my Meguiars detailing forum as well as AutoGeek online and a few others.
Watched a lot of his videos...even the ones where he's driving his Vette on the track at Atlanta. Lots of good info in his videos. Now that I have the Porter Cable polisher, I'll need to get a refresher on using it via his videos.
