Hull fixing tips/advice

OK, the hulls that we got for free with the holes in it and ready for repair. Looking for last minute advise on fixing the hulls. I have epoxy, bi-axial fiber cloth, fiber mat, peel ply, fairing compound, marine-tex, and gel coat.

For the two "holes", I saw the tip to insert a piece of cardboard with a layer of fiber mat folded, inserted, and pulled against the inside of the hull by string. I think I only need to do this for the one big hole.

For the others it looks like the steps are clean area with acetone, cut and place layers of epoxy infused fiber mat pieces from small size to increasing sizes until almost hull surface level. sand area flat, hand paint area with gel coat, let cure. hand sand the gel coat and surrounding area.

For the non-hole areas, just cover area with gel coat by brush?

Do those steps sound correct? Would you use any fairing compound?

For the deep scratches, would you just clean with acetone and then paint on gel coat over the scratch?

You probably won't need fairing compound if gelcoat does about the same, but if you do, make sure it is compatible with the gelcoat.

cut and place layers of epoxy infused fiber mat pieces from small size to increasing sizes...

isn’t it supposed to be the other way around? I think you want biggest pieces with max surface area directly over the hole.

I had seen it demonstrated the other way, your way makes sense.

You need fiberglass filler. The smoother and more finished
the surface the less hassle getting a professional looking gel coat.
Gel Coat is non leveling so you'll still need to do some final work
but it will be much less.
