I have some water spots from the sprinkler system here in Las Vegas. What wax or rubbing coumpound should i use? Also do need a buffer? It's not bad but want it off.. Thanks

You don't want wax, you want to clean it real good first. Wash it, then you should use a clay bar and see if that gets rid of it. If not then you can either use a mild cleaner/polish by hand or dual action polisher. If the spots are STILL there after that then DONT DRINK THE WATER IN LAS VEGAS.

Thanks
