In Response To: Epoxy: epoxy vs polyester resin (John Umlah)

: Hello all: I am about to begin the glassing process. I have been to a local
: supplier to price out the epoxy. I was wondering, First, is it possible to
: glass the outside with epoxy utilizing it's strength and asthetic
: properties while using ployester resin on the inside? THis would prove to
: be a considerable cost saving. My concern is can galssed epoxy be joined
: to a glassed Ployester resin surface? Are they Chemically compatable? are
: the strength properties of Polyester resin compatable with epoxy? I know
: that is is alot to ask but I am guessing that others have had experience.
: I appreciate any input.

i have read that polyester shrinks a bit more than epoxy upon curing. if there is some time between glassing the i/s and seaming the yak all toghether, it may make even more sense than usual to leave on the forms or leave in spreader sticks while waiting to seam. upon completion, it may be that it will tend to delaminate from the i/s more than if epoxy, therefore store with hatches off so is well ventilated and water infestation is minimized.
