I was at fiberglass coatings in St pete the other day picking up some gelcoat and got into a conversation about transom replacement and core materials. The guy mentioned Arjay 611, or pourable ceramics. He said the strength/ rigidity/tensil and compression was far better than wood or other cores plus it will not rot lighter too. Instead of cutting out the glass skin on the transom you take the cap off, drill/grind auger the wood out, so you are left with a hollow transom two fiberglass skins. than mix and pour the ceramic, he said a 23 would take 15 gal, @ a cost of about $160

Has anyone tried this method or heard of it? He also said this can be done with stringers as well.
