Spray painting hulls.
I couldn't see the point in paying for epoxy tissue so I bought a huge bag of J cloths from Poundland and used that with epoxy. Slarred the epoxy on the mahogany hull (made from old chair legs my Grandad had made a dining suite with) and then laid the J-cloth on the tacky epoxy and slarred more on with an old credit card. All my credit cards are old now and a damned site more useful as epoxy squeegees than they ever were before. Got a few ridges where they overlapped, but filler sorted that out. The hull is still very light, so will need all the large lead weights on the end of a long fin keel (removable) as it carries a big rig, (see avatar).
Good luck,
Martin
