A precoat layer of epoxy would increase the weight, but only minimally. If you are worried about counting grams you can apply the wet carbon directly over the foam but at that level of weight watching, you will also want to be bagging and pulling vacuum on the parts to eliminate any excess epoxy. The foam I used didn't absorb the epoxy to any noticeable extent.
I used an insulation foam board, available at most hardware stores. It comes in large sheets. I used carbon fiber directly on the foam. You could coat the foam in epoxy to make it stiffer before you do the carbon fiber and compression wraps.Y gracias a google translate - he utilizado un panel de espuma de aislamiento, disponible en la mayoría de las ferreterías. Viene en grandes sábanas. Utilicé fibra de carbono directamente sobre la espuma. Usted podría cubrir la espuma en epoxy para hacerlo más tieso antes de que usted haga la fibra del carbón y los abrigos de la compresión.

Way to go making your own, but a quick installation note. The way you have your fender mounted will interfere with the suspension fork travel. If you were to mount it to the arch of the lowers on the fork like this, it wouldn't interfere with the suspension action. This is the way the "buy it at the store" versions get installed.
