We are ten seniors building Wood Ducks at our local Senior workshop. The project has been great and we are now in the later stages of our builds. There has been no difficulty in wetting out the fiberglass cloth. But, some of our subsequent coats develop an orange peel effect. This seems to appear only on one side and covers the entire area i.e. tops or bottoms. Some of the boats have a clear flat almost perfect finish and then the other side gets the orange peel effect. We apply the cloth wetting coats with a spreader and following coats with a West Systems foam roller and a natural bristle brush. We tried going back with a spreader to see if the surface would flat out only to have it come back with the orange peel. Is there a recommended wipe down prior to coatings? Is acetone so volatile that even in the same room it will contaminate the surface? We tried a wipe down with a damp cloth and use no solvents or acetone except for cleaning brushes and tools. After searching previous, posts I find few ideas. One builder couple who thought they were doing every thing right had resigned themselves to lots of sanding and a lifetime of aversion to using epoxies! Thanks for any help Keith.
