Testing the paint sealer

My plan is to fill the bottom holes, sand it and repeat until the surface is in the best shape.

Once this step is completed, I want to cover the boat's exterior with Petite Red Mahogany sealer, sand it and apply a layer of epoxy on top of it followed by applying the fiberglass before finishing with 5-6 coats of varnish.

Basically I want to give it a uniform color before applying the fiberglass.

Have considered double-planking if the finish will not be good enough, but this involves the build of several frames inside the boat to support the planking weight.

Tested on a small area after the first holes filling and sanding. The darker area on the right shows the epoxy underneath that has not been sanded.

Oct 23rd, 2015: Sanded all the boat to remove epoxy. Boat is now ready for filling only a few areas for the second time.

 

Advice: Sand all the boat nicely, eliminating the epoxy layer if you have one.

Will continue with the project in the spring of 2016.

Covering the holes on the hull

Turned over the boat and covered the holes with resin putty.

Sanded it with sandpaper no. 80.

Covered the screws at the transom's edge.

Decided to remove the screws from the butt blocks and filled them.

 

After sanding the first fill coat.

 

Advice: Sand only in the direction of the wood grain and try to not scratch the surface.

 

I have bought a Dewalt random sander: huge difference. The surface looks great, it is even and the texture of the wood recovered from under the epoxy.
