Re: Sunscreen and Gelcoat?
This is also an example of different types of boaters and the boats they prefer. My boats are for hard recreational use (including transportation) in hard conditions (dirt, mud, salt air, fishing/hunting) so I wouldn't even worry about sunscreen. My boats don't look shiney new but anyone can do almost anything in them without getting yelled at. The time and money that others spend on cosmetic maintenance and care, I spend using the boat.
There's no right or wrong; the car analogy fits. How you use, protect and treat a "car" changes from the garage-kept sunny day only Corvette, the keep it nice town car, the child-tested minivan/stawag parked under the trees, and the farm truck.
