So....everybody i watch seems to mix Smooth On at 1:1 ratio, but the label clearly speaks of increased heat resistance and durability at 1:2. Anybody have experience with that ?

I always mix a bit more resin to hardener but mostly just to be sure the mix is "right".
I don't think the heat resistance is that big of a deal. I have left my bows strung in a dark colored car on 90* days in the hot colorado sun and none have ever come apart.
Are you getting ready to glue something?
I built a kids bow form, R / D and am running the first make up using stuff I have on hand. With luck it will work out. I did a dry run but i may have to tweak my next build. Might have gaps in the usual gap spots.
Chuck,
I used the 2:1 mix ratio specified on the cans for several years. It worked just fine. The trouble with the ratio is that they don't sell the glue that way.
Kenny's archery was willing to sell me glue in the 2:1 ratio. Basically 2 cans of resin and 1 can of hardener.
After several years of experimenting, I could find no real advantage to the ratio for my bows and so I found it wasn't really worth the bother. I went back to the 1:1 ratio to make buying the glue less bother.
It's irksome to me that smooth-on touts a mix ratio that they claim is superior, but they won't support it by their packaging.
I agree Steve. Seems wierd. The bow is out of the oven, rough shaped and i am building up tips and handle dressings. The glue joints came out better than i was dreading. Not my best, but not bad at all. Shaping the tips tonight and making a string for tillering in the morning. Baby steps.
