Is there a proper layup or is there more than one way to skin a cat?

Wow, my original skin wasn't even close to 3/8" thick(more like 1/8")I think you'd be ok with just using the thickened epoxy. The only reason I used a couple layers of 1708 was because the outer skin seemed to be quite thin,so I wanted to beef it up a bit.
If its an out drive powered boat,the transom can only be a max of (i think) 2-1/8" thick.After I finished mine with the two layers of 3/4 plywood,- the putty,-and the new glass skins- on the inner and outer transom skins,I was at 2-1/16" thick
I went too heavy on the putty as you can see on the picture of the core
Its the first wide grayish band that you can see on the picture of the large core sample. on the right side.
It didn't hurt anything structurally,although it added extra weight.
