Re: Hull and Deck paint over fiberglass
Hiyas Wild.
There are alot of " non skid " coatings available from rhino liner to what Sasto said Awlgrip ( Top of the line but expensive after reducer and converter costs ).
I prefer Gelcoat with Extra cource "Griptex" ( us paint product ) added to it. Just mix and roll on.
IF you wanted gel there are some things your going to have to do and be aware of before you start. let us know if gel is even a consideration so we can guide you further.
Any way you choose I would suggest you do a test panel with before you start rolling or spraying it on your new deck

.. juuust to make sure kinda thing...
As far as paint for your hull and topsides. Knowing what kind of paint thats on there now would be a great help.
Without knowing whats on there your left with 3 options. 1. sand the paint off to origional then prime and paint with whatever system you choose. 2. prep prime and paint. Or 3. scuff and paint.
#1 is the only surefire way of Knowing the application. #'s 2 and 3 are kinda roll the dice ways ..
Pics would be helpful if you have any.
