Well this is my first post here. I've been using the site for many years on various repairs. I am confused about something. I have read many posts on deck and stringer repair, and I am doing my first deck and transom repair on a 25 year old Center Console. A very simple question. Should I lay down CSM on the deck before my next layer of roving or cloth? I read yesterday that the CSM is a waste of time and money. I am using ply and poly resin. Should I just be using a combo fiberglass cloth?
