    I would use epoxy two-part mix with color apply with a brush. Just degrease areas and little mild scrubbing with sandpaper.

    I hate that splatter-coat stuff (the random dark globs in the photo above).... sometimes I wonder if it's just put there to hide anything that didn't go quite right in the production line, or to hide oil leaks or something.....

    If the damage is only in the coloured surface and not in the structure itself, I'd probably stick with what "mydauphin" suggests.

    so the epoxy would be used how? to fill in the areas where the fiberglass is showing? what type of paint would I use after that?

    thanks in advance for everyone's patience, "newb: doesn't even begin to describe how green I am.

    The upper area looks like air. Air is when the part is molded and the fiberglass is not against the gel coat, leaving air pockets. This will happen often in tight raduses. You can brush some gel coat on it with surfacing agent, it is only cosmetic. The black splatter stuff is called webbing solution you can make it out of black gel coat and webbing solution, if you want the area to be uniform. The area by the drain holes looks like delam, (delamination) that is where the lamination separates. It happens a lot on transoms. You need to grind that area clean and lay it up with with a piece of 6-8oz fiberglass cloth sanwiched with 1.5oz mat. The mat will give it a better bond to the surface, keeping out air bubbles and make it less noticable when you paint it again. Again, mix up some gel coat with surfacing agent, spray the area and follow up with the webbing solution again.

    so the white stuff in the picture is gelcoat? I really dont want to spend much time or money on fixing these areas. I guess I will probably leave the project to whoever buys the boat, cant imagine it will drop the value that much.

    Yeah, by the looks of it they sprayed the inside with gel coat and surfacing agent, then went over it with webbing. The area on the top you can just mix a little cup with gel coat and surfacing agent and brush it on the area. With the spot above the drain holes you should probably grind of the gel coat and patch it. You can then do the same thing, and brush on some gel coat with surfacing agent. If you don't use surfacing agent the gel coat will be sticky due to the fact it was created to be sprayed into a mold. (airless environment)

    Gel coat is the easy solution, for the black, use a Sharpie and just copy the random pattern.

    Yeah, that might look good enough to get it sold!
    If it sells quickly.
