Man Drew, that pic is awesome, dripping!
As we all know, its usually 90% prep and 10% products we use, kinda.
Either 26 or S100 can be used on either. I have used S100 on lots of colors. It is a great "neutral" type wax, meaning, doesn't really mess with the color of the paint like many do. This is why I use it on lighter colors as it doesn't darken them up. I knwo many will yell at me, but I just don't like it that much at all, then again I have so many waxes to choose from.
I like the Megs #26 for darks, becasue after a day, it starts getting this glow about it that I can't describe. I actaully started a thread abotu the glow on another forum recently. Remeber, I got the #26 on whim and didn't expect much, almost didn;t use it.
I am waiting on some Collinite so I can't comment there.
All I know is, if I ran out of wax, couldn;t ever mail order any, I would buy the #26.
Drew, if you end up going different routes, let me know and I will gladly send you a sample of each, just pm is needed.
