I am trying to bring back to life a Starboard Freeride Foilboard. It was given to me for free when I bought a seized starboard foil (fuselage/mast were seized). The board has many small holes and 3-4 big holes near the nose. I don't care about aesthetics. In fact, all my boards sport small repairs that are not painted.
Do you think two layers of glass (maybe one of carbon and one of glass) could be enough if I'm not sanding? I might slight sand and then apply a clear hot coat (is this the term?) in the area. I believe the glass I have is 4oz and the carbon is 6oz. I could add a third layer but none of the repairs are structural. Thoughts?
We don't know, the boards constructions or the size and nature of the damage.
If it's just surface damage to fiberglass, the 2 layers of 4oz will be fine.
If it's sandwich construction, and the damage has penetrated to the core, then it gets more complicated. Some pics would be good.

This is the worst part of it:
There was a hole that I filled with gorilla glue (foam) and some parts that were delaminating that I needed to remove. I'm thinking about putting three layers there.
Simplest repair is
Tape off area
sand and tidy up damage
mix resin with q cells to a whipped cream paste
fill hole (over fill)
-when cured-
sand to shape of board
Laminate 1-2 layers of glass cloth
sand
remove tape around area
finish coat.
Also, do you think the fiberglass will adhere to the paint if I sand the paint a little bit where the Tiki man is and lay some fiberglass? Or I should never lay fiberglass over paint at all? I always sand all the paint before glassing but wondering if sometimes we can get by with a little overlap.

No, the glass won't adhere to the paint, need to sand all of the paint fronm the damaged area. But don't sweat it too much as with that construction, the rest of the board will be delamming shortly.
All good stuff above but I will add
gorilla glue foams with atmospheric moisture. Needs water to cure. Then like most products, heat helps. Don't use it for deep fills as it might still be liquid in the bottom.
had a repair recently where a previous one by a "pro" had expanded a year later when it got moist n warm, so had blown 1/3 of the bottom off a beautiful SUP
if u did a deep fill at least introduce a little moisture to the core next to it and cook it in the sun a bit before laminating
Thanks, all, for the replies. Mark, I filled the deep hole (maybe over an inch?) in several stages. I mixed the glue with water and poured it in the hole, let it cure and repeat. I then sanded flush and applied a coat of epoxy with thickener (west system microfiber or Cab-o-sil) because that foam is super porous. I did this probably a year ago and today I decided to continue working on it.
My only goal is to have a water tight board to give it a try. My only foil board is 76cm and 124l (Roberts flight GT), I use it with the IQfoil foil (1000, 800, and 650 wings) and I always wondered what is like to foil with a wider dedicated foilboard. This board I'm repairing is 85 cm wide and 144l.
You did it the right way, mix glue with water before cast so it all foamed to avoid what Mark explain.
This starboard seems to be a light black tint glass lam over sandwich foam. I would sand all, seal/fill with a qcell+cabosil+resin spackle then sand flat. Lam 2 layers of glass with tint.
