I use 303 on my fiberglass roof.
I never let it get too dirty.
On my hand and knees, I spray it on and wipe with a paper towel.
Working from front to back where my ladder is. I do not stand up.
My roof looks like new. Gelcoat is like new. No caulking using my method.
Has a pretty good shine and last fairly long. Even in the rain.
