Dear friends ,
My friend have much trouble with laminating the strip canoe hull . Bubbles . He remove glass , sand and made new laminating- bubbles again. Removing again, glassing and the same problem . He was start with epoxy. One old boat builder some years ago for laminating canoes was used varnish instead of epoxy . My friend try this method - bubbles again. He have not loosed optimism not yet . May be some boat builder have some experience to work with varnish instead of epoxy and will be so helpful and will share with some information . Thank you .
