The osb is a roofing type that comes in 2' x 8' tounge and groove so it does not need the joints covering, The Fibre glass is 450g/m2 single layer with resin for roofing, It just seemed to flow better and and grey flow coat to finish, It's not something i do alot of but it went ok, I still have work clothes with resin on and the day i did that i had to soak my knees in acetone to get my jeans off....
