Ok i bought the fiberglass resin today but, is the cloth really needed to seal the hull. I plan to put at least 5-6 coats on. As descibed in my plans i recieved. It says to apply 3 coats of clear dope (but fiberglass would be ok i think) then sand with 320 wet or dry. Then apply 3 more coats sand agin. Then paint. Is this ok. Or should i get the cloth too. Remind you i don't have a work shop and have to work outside (if weather holds back).
