I also went the Bob Moses route, and I consulted with
@CaptainGizmo prior to doing so. He has already hit the highlights I would have in this thread.
The only thing I’ll mention concerns the above quoted comment. I think the result he’s referring to is not possible if you live and/or travel east of the continental divide.
Driving through rain puts a coating of road film on your coach that, in my experience, requires no less washing effort than before. It still takes me 1.5-2 hr to give my coach a thorough cleaning. With that said, I’m happy with the results of the Bob Moses process and product.
I just returned from traveling the Ohio and PA turnpikes. I’m parked in my driveway waiting for a break in the weather so I can get rid of this crap.
