Does anyone know of anywhere that I can buy around 5 or six letters of resin form fairly cheaply? Well cheaper that a chandlers. The other thing is that I understand that West system flexes slightly when it is cured which means that it is not brittle. Does anyone have any comments on whether this makes a difference I want to firstly sheath a dingy hull and secondly seal a gap between a steel transom plate and the hull where moisture is getting in?
