Nice!
If you want to keep it easy and fast, then buff out the top cap, anything smooth, with a good marine one-step cleaner/wax and a wool pad on a rotary buffer.
There's lots of thin sections on the top cap on boats like these in-between the non-skid sections that make it a real pain in the butt to buff these areas out.
In my marine detailing how-to book, I actually show taping-off the non-skid areas otherwise you're going to run the buffing pad into them and fill them with compound, polish or cleaner/wax - whatever it is you're using.
You can also do all this work by hand to be more careful but it will take longer.
There's no quick, fast or simple way to buff out these kinds of boats.
I know that's not the answer you're looking for but it's the truth.
