Aeromarine 300/21 epoxy ?

[JeffBurris]

I already have a ton of Aeromarine expoxy resin with the non-blushing #21 hardener. I don't have $$ really to be buying different expoxy if this will work. Though it's so often used to cover bar tops and finish boats, it's very often used to make fiberglass and carbon laminations (boats, dashes, surf boards). According to tech support there, it's great for wood to wood and/or glass to wood etc...
but I'm wondering if it will hold up to tension, compression, and general flexibility. Some say they
use Aeromarine but they tend to mention either #11 hardener that's colored because it's mentioned anecdote-wise that it's a "bit stronger, thicker, and flexible"... as far as viscosity I kind of like the idea of it soaking into pores a bit with the #21, as it's still a bit thick, after all it stays on bar tops up to 1/4" thick in one pour... others mention #400 resin but they allegedly only sell that to industries.
Here are some specs of both 300/21 and /11 I'm not sure what the flexural strength means, it makes the 21 look stronger, but maybe moot if it's stiffer in a bad way not allowing the bow to bend without breaking down -- I guess the proof is in the pudding if I boo back a self bow and it hold up for a few hundred shots:

Aeromarine 300 resin with non-blush 21 hardener:
Specifications:
Mixed viscosity: 600cps
Color: Clear
Work life: 30 minutes@70F
Cure time: 24 hours@70F
Shore D Hardness 80-85
Shear strength: 2500 psi
Tensile Strength 10,500 psi
Flexural strength: 17,500 psi
Modulus of elasticity: 5.7 x 1,000,000
(again the 300/21 is what I have lots of, as opposed to /11 -- )

300 resin w/ 11 hardener:
Specifications:
Viscosity: 3000cps maximum
Color: Clear Amber or Black
Work life: 45-60 minutes@70F
Cure time: 24 hours@70F
Shear strength: 2500psi
Tensile Strength 8000 psi
Flexural strength: 12,800psi
Modulus of elasticity: 5.7 x 1,000,000
said to be a bit more "flexible" than with the 21 hardener in an anecdotal comment
on another page.

Heres what I think.I've sold a few diff types of epoxy over the years.They all worked for bows. Some were less forgiving in mix.Some not forgiving at all in mix.Some would shoot for month before it let go. Try to figure out what went wrong then and hope you didnt glue up 5 more bows before that.Smooth-on is the way to go its just proven over and over the best way to go.Thin your epoxy with lacquer thinner and try it as bow finish. Good way to use it up.
