Use only "fresh" polyester resin. In other words go to a boat repair shop for your supplies, not the corner hardware store.
I would use woven roving fiberglass and apply the mix as necessary but not flooded. Just wet the material as you push out the bubbles. Be sure to wear old clothes and long sleeves with rubber gloves. The odor is not too bad. You should not get a "buzz on". Adequate ventilation would be helpful. Hope this info is helpful.

Ride safe.

I have replaced a few wooden transoms in boats before. This is base on my best recollection, which came from a Doc. from the fiberglass supply store.  The matting gives the best adhesion and the woven cloth gives the best strength.  I use both on the transom,  one layer of mat, then the next layer of cloth, then another layer of mat, then a layer of cloth, and so on.  Depending on how strong and thick you want to make it.  I used two different polyesters, the blue and the red. The blue remains tacky while adding layers, the final coat is the red that gets hard not tacky.  When I prepped the wood, you take the Poly, and add the activator/hardener per instructions. Once mixed, you add acetone to thin it to water like consistency, and roll it on over all the wood so it will soaks in, and let it dry.  Then using the blue, tacky Poly coat the wood, and I use the first layer with mat and roll it, saturate it and  then when it hardens, I put another coat of Ploy, then a layer of cloth and roll it, saturate and let harden and repeat till you get the thickness, then the Last Coat, use the red hardening Poly. And let it get hard and you are done.  The smooth surface on fiberglass things like boats is called gel-coat.
