Has anyone on the list used Aeromarine brand epoxies?

They are available at http://www.jgreer.com

I seek feedback from users.

Off topic, since I haven't used that brand:

When it comes to low-cost general-purpose epoxies, I prefer the 635
system from US Composites (http://www.uscomposites.com) with 3:1
medium hardener.

In the 2.66-gallon kit, it costs about $30 per gallon (about the same
as polyester resin at the hardware store), has a nice 3-hour working
time for thick layups, and I've had good consistent cure from it.

However, I cannot attest to the strength or other properties of these
materials. I've been using it only for tooling parts, so I don't
consider it of great importance at this time. I'd want to do a coupon
tests before I used it for any sort of flight or structural article.

Thanks, and best regards to all

I have not started building my plane yet... haven't even settled on a
WHICH plane... but I have used US Composits epoxy to build a canoe from
scratch and can attest to it's properties. It appears to me to have
every bit of the strength of West systems epoxy for about half the
price. The only downside is the shop really needs to be at least 80 -90
degrees for it to cure in a reasonable time. I live in south Texas, so
that's really not a big issue for me. I have no idea about heat curing
etc as I've read needs to be done for aircraft layups, but the guy in
florida who markets this stuff seem very knowledgable on the phone.
Their URL is http://www.uscomposites.com/.

I would be curious to know what is special about "airplane" epoxy vs
West system or East system etc... or is that another on of those things
that they make for airplanes and triple the price??
