Thanks for the info!

I will go with the polyester then, as the main concern is UV stability.

Second are clearness of the coat/layer and adhesion to wood and the
fiberglass (polyester, I assume) of the hatch. Strength is not an
issue, none of this is structural.

Any concerns with that from anyone? (Double-checking before I putting
sticky non removable stuff on large visible parts of the boat.

Thanks!

Your reasoning is backwards. First epoxy will stick to either wood or old
polyester far better than polyester will. Second, West 105 with their 207
clear hardener reinforced with a 2oz scrim will be clear with a slight
varnish tint and third it may not seem "structural" but the teak/holly will
continue to expand and contract with heat. Epoxy with a glass scrim will
hold together but polyester will not. You will be taking 3 steps backwards
if you cover it with polyester. 207 is self leveling and has a UV filter in
it but 2 or 3 coats of UV filtering varnish on top is recommended.

I am not sure what to do about your "simi-transparent" hatch. Nothing is
going to restore it to original. You might try sanding it down to get a
reasonably smooth surface and then flowing on a clear 2 part Aliphatic LPU
such as Progressive Epoxy Polymers. Regular laminating polyester is not all
that UV resistance. Most UV resistance comes from the pigment in the gel
coat.

Another reason to go with epoxy. Polyester is much less flexible and more
brittle that epoxy. Believe me, the poly will fall of all by itself. Been
there, done that.

Yes: polyester does not stick to wood., it might look like it, but you peel
it off very easy. Polyester also does not stick to cured polyester very
well. Use epoxy. Period.
