Last four times out it has been rain and thunderstorms.. I forgot to take the canvas out of the boat after it had been put away wet.. When we put the canvas up last night, the Eisenglass had some spots that looked like blue haze.. I tried 303 protectant (all I had w/ me) on the spots/areas and it didn't touch it.(some areas are pretty large). I have some Meguiar's mirror glaze #17 clear plastic cleaner.. Anyone know if this stuff would be o.k. to try on the blue haze areas? If not, can someone reccomend a product or is it ruined.. thanks
