I disagree that there is no reason to use wax.
I use 303 on my outdoor gear, kayaks, and vehicle trim, and it does works nice. But it does not produce the same result, nor does it seem to last as well as the wax application. I do prefer it on the upper textured hull surfaces. Does not do so much on the sides.
Wax will not hurt polyethelyne, and it makes a great cleaner. I used a mild cleaner wax (Nu-Finish) on my Wave, and it removes grime, scum lines, rain streaks (which previously I had been unable to wash off even new), and even polishes it to some degree. It has a decent shine which it NEVER did, even new, and feels much smoother than before. I used my power buffer to apply and buff the wax off (2 seperate bonnets) so I am sure that method helps w/ my result.
Consider this: if you view the polyethelyne surface under magnification, it is slightly porous. So, a small amount of wax probably stays in those 'open cellsl', making future cleaning easier. White wax on a white hull is invisible.
I performed this recent 'wax cleaning' a couple of weeks now, and I noted that during the rain, water beads cleanly off the hull, where prior to that it jus sort of sheeted.
Even if it does not 'stick' the same as if it were gelcoat or paint, it is still there, and I am very pleased w/the result. I can always repeat the process every once in a while. Future cleanings should be easier.
Worth a try anyway
