Welcome aboard. I agree on the decks about removing the teak. You will probably have to do some recoring the decks. We have fiberglass decks except our sundeck but it had stress cracking all over the decks due to the gel coat being too thick. We sanded off all the nonskid and painted the decks with Kiwigrip. Very easy to work with and will hide a lot of minor imperfections in the glass work. Good luck. And we will need photos of the work.
