lots of opinions on that one..

we use meguires quick detailer after every trip and wax once in the fall and once mid year again with meguires. interior has only ever been babes or 303. we use malco cleaner for tough stains when we have had them BUT malco strips the uv so you have to apply babes/303 after cleaning a stain.

I ended up with a bottle of speed gloss from boat candy a few years ago. guy in WI turned me onto it and kept his boat looking good. it works well but honestly I'm not disciplined enough to buy it ahead of time. easier to pick up meguires when doing our weekly grocery shopping at walmart and I don't really see a difference.

tons of the guys use hula and hot sauce/boat bling/etc. Rc's boat always looked amazing in the pics so sure it works well but never used any.
