Someone recommended the PS35 to me, said it was lots better than Aqua buff. I thought aquabuff was great! It was cheap and worked better than the 3m stuff I was using. The 35 is 3x the cost of aquabuff but if it works better it will be worth it. Anyone else have any experience with the 35??

I can only speak on the Polar Shine as I have not used Aqua buff. It was far superior to the 3m and Meguiars I had been using. I am by no means an expert when it comes to finishing products but am very impressed with Polar shine.

How oxidized is the fiberglass you will be polishing?

I bought the vibra cut. Polar shine was way expensive. The colored sections I'm having to wet sand. the white seems to buff out ok.

I find the polarshine line works best on sanded freshly sprayed gelcoat, but on older gelcoat it falls short. Even if you sanded the old, existing gelcoat it does not work well

It does keep your pad clean and what flies off the surface is fairly easy to clean as well compared to the 3m High gloss gelcoat compound.
