If this is a dumb question feel free to say so.
I am thinking about doing a transom repair to the boat that's been sitting in my driveway what seems like forever. I'm having no luck selling it for the value of the motor.
The transom is rotten. The keel is split. The outer skin is ugly to the n'th degree. What I wanted to do was use the outer skin as a backing surface to do the repair. The plan was to cut the splash guard out and remove the inner transom skin and the rotted wood. Grind out the hull and bottom from the inside to a taper that almost cuts the outer transom skin off. It would be almost like using what's structurally bad as a mold.
So far sounds challenging, I know.
At this point I would mask off the edges and sides of the hull and apply mold release to the inner surface of the outer transom skin. Then un-mask it to begin the lay up process.
Here's the meat of the question now that you have a background. If I were to lay up 2 layers of 1 1/2 ounce chopped strand mat followed by 1 layer of 6 ounce fabric as my first application could I use the following resin: For the first layer only use waxed poly resin followed immediately by the next layer of mat and the layer of fabric with unwaxed provided that layer 2 and 3 are applied before the first layer kicks? I would be following that with 4 more layers alternating 1 mat and 1 fabric.
If I were to do it that way would the wax be far enough away from the 3rd layer that when the third layer kicks I can apply the following layers and still have them form a chemical bond? I don't want to do it all and have to worry about it all delaminating. At the end of the job I want to be able to grind the edge of the original outer skin and have a nice smooth paintable surface.
Or am I just dreaming? Otherwise I would do it all the same except for the first application being waxed and after cutting the original skin I'll lay up an additional layer of CSM with the waxed resin as my final application.
