who has used it? i need some serious info about this stuff

my smoothie II's are at the end of my patience. i keep them cleaner than anyone..polished and everything then one weekend of rain and crappy weather they are now covered wtih water spots and stains, however they will all come off with tons of effort. i am willing to put in the effort to get them clean again but no way in hell im not putting some kind of sealant on them..

so has anyone used zoop seal or similar prooduct that can shed some light on it for me..

thanks

What if you put wax on them?
