Just a Tip......
Not all Rust-oleum products are the same.
Rust-Oleum Marine Coating Topside Paint
is specifically formulated for use on fiberglass and goes on right out of the can, smooth and sweet, using the roll and tip application method. Other Rust-Oleum products are more consumer grade.
I used the Rust-Oleum marine product on a pop-up trailer I restored for my son and it's "almost" as smooth as the 4X more expensive Interlux Briteside Marine paint
I used on the Hunter.
The Marine product may be hard to find in stores, but is readily available on-line through Amazon etc.
