That stuff does work good on the cladding but you have to be real careful not to get any on the paint. That's one of the things I like about B2B - you can be messy & not cause a problem.
EDIT: Sorry, I forgot. Grats on your purchase CatFish. I feel for you though. It's hard to have that beast sitting in your driveway waiting on title & tags. I had mine for 2 weeks before I could drive it.
