I suspect there is not much difference between boat wax brands. My boat dealer recommended something with carnauba. I've used Meguiar's boat wax on my ski, but only because I got a free bottle at a boat show. It has carnauba plus synthetic stuff...........sounds good on the bottle. I guess it works OK, but I've never tried anything else on the boat or ski. Goes on and off like every other wax I've tried.I am a new PWC owner and I was told by the dealer to give it a good wax job! My dealer did not suggest a brand to use. I was wonder what brand of wax some of you guys have had good success with ie Mothers boat was etc. Thanks in advance!
