To be honest we've not found that the two pack epoxy that we had on Albion's hull was particularly any more long lasting than one pack finishes. Another down-side of two pack that we've found is that it rapidly weathers down to a dove-grey colour. Not a huge problem in itself as it is an even colour all over. If you do need to touch up scrapes etc though, you can't easily use two pack due to it's specialised nature and one-pack (such as International Intertuf) shows up very black against the grey background. This means that you end up a with a patchwork quilt of black touched up areas on a grey boat. Just a thought. Certainly my boat-builder, who originally did the hull in two-pack, doesn't recommend it any more and is using one-pack. Roger
