Subject: Re: [Star45] Epoxy resins and hardeners for glassing hulls
The best way to save $$ on epoxy is buy larger containers. I used to buy the qt's and now I buy the gallon resin and qt hardner. I use 10 to 12 pumps which I am told is 1 oz/pump to do 2 layers of 3 oz cloth. So one layer of 9 would be 15 to 18 pumps. So one quart will do more than one hull, probably 2 or 3 if you stretch it. I use IPA to thin the epoxy for sealing the inside, but I would not do that on the outside with glass. If the epoxy gets too thin you get a lot of pin holes. You can also make the epoxy thinner by adding heat with a hair dryer. Adding heat will make it kick faster, so this can really impact your pot life on the 205 hardner. Also tall narrow containers will reduce pot life. I used 207 which is the most UV stable hardner on my last hull.

the current prices. What is the best way to save on buying resin and
hardeners.
How much resin is needed to saturate one or two layers of 9oz cloth on
a Star45 hull?
Will a quart of west 105 and .44pt 206 hardener do more than one
hull?($50.00)
An earlier post mentioned thinning epoxy with alcohol.
Good idea yes/no? What is needed for clean up?h
