Time Will Tell
July 10, 2018
I have a 30 year old cabin cruiser that I've been struggling to keep the oxidation at bay. Two years ago I used 3M products and struggled using the product period, although this may have partially been my fault due to some fiberglass inexperience. When I was finished the boat did look good; however, after a few months it oxidized again. Last year I decided to wet sand above the rub rail. This made me extremely nervous seeing all the blue in my driveway. I followed this using the same 3M products from the year before and the results were definitely better. The oxidation returned again, although not as bad.

This year I decided to purchase the Marine 31 brand and used a rotary buffer for every step instead of a random orbital. This stuff is crazy easy to work with and the results were amazing. I've been down this road before, though, so time will tell. I used Lake Country CCS pads and followed the Heavy Cut Oxidation Cleaner with the Finish Polish and the Sealant. The boat seriously looked like new! Let's hope it stays this time.
Very easy to work with - product does not dry out super fast A bit pricey, especially if you have a larger boat
