Spread a coat of Total Boat Fairing compound over the sanded fiberglass top and bottom.
The first of many coats

After sanding down the fairing to eliminate high spots, I got to work identifying air voids in the glass.
Nothing to do but circle them with a marker, use a dremel to cut them out and bevel the hole and fill with epoxy resin thickened with microballons.

Yes I had to do this more than once. I think I will stick to wood from now on...

After fixing all the air voids, spreading another coat of fairing compound and sanding down through 400 grit, I shot a couple of cpats of primer.

Let me primer cure, then I will shoot the hull bottom with gloss white.

I thought I was done and ready for paint, but i found more air voids and fixed those.
Then I thought the keel needed more protection so I glassed in some aluminum angle that I heated and bent to shape and cut into sections.
Epoxyed that to the keel and glassed over.

Then I decided since I had more aluminum angle to add that to the stern corners.
Epoxyed those down as it was only fiberglass and foam on the corners.

I installed epoxy covered plywood inserts to hide the framing and filled the voids with expanding foam.

Will eventually fiberglass over the wood with 4 oz boat cloth and cover with a textured bed liner spray.

Finally fixed all the air voids, sanded down once again and re primed again.
Real painting is next.

Sure looks good. I like the angle iron touch. I have never tried to heat, bend and epoxy it though. Pretty sure I'd make a mess of it :roll:

Yes it wasnt easy.

I had to cut some scrap pine in the same curve line as the keel.

Then use a torch to heat the aluminum up and beat it to shape over the form.

Even then I couldnt get it bend as much as I needed, so I cut up the angle piece and fitted it to the keel one piece at a time.

Marine epoxied it in place, the fiberglass over that. If it comes off after all that then I quit.

Shot mulitple coats of gloss white. Then let it cure for 3 days and start laying down the tape for the blue stripes.

After the blue, I will spray it with an automotive high gloss clear with hardener.
