Hello, thanks for the replies,to answer,many old fishing trawlers,used to have thier decks ashpalted,I am thinkinking about it, because my old wooden deck is so knackered,but still functional,so I cant restore it to that lovely oiled or varnished state, without replacing 90% of it!! IT leaks in summer but not winter,it is also and old trawler that I am restoring,and I have problems wetting the deck every day,as the engine and pumps are not yet in a working condition! regards TAG
