Thanks for taking the time to prepare such thoughtful and detailed notes. All makes good sense and sounds like advice i need to follow. Just to clarify a couple of details. Since my hull sheer line strip and deck sheer line strip are currently touching (not glued together but in apposition) on the forms, there is no way to insert masking tape between them, only to cover the outside surface of the strip with masking tape. So I will invert the forms, so hull up, tape the garbage bags (or I was thinking a plastic drop cloth) so that the deck sheer strip is completely under the plastic and about half of the hull sheer strip is covered with the masking tape holding the upper edge of the plastic. What I'm not clear on, is what keeps the epoxy and fiberglass from trapping the masking tape between the glass and the wood of the hull sheer strip. I'm also not quite visualizing what you were talking about with the carbide scraper and tapering the glass. Could you try to help me with that? Also, the spreader strips - how rigid do they have to be? I mean, can I use scrap pieces of the same strips that have been applied to make up the hull (1/4 in thick x 3/4 in wide)or do they have to be thicker pieces of wood to resist bending forces? Thanks again
