I've laminated with the 1:1 and it worked fine, but it does take some convincing to get the glass saturated vs. a thinner resin. With the thicker it's also easy to use more resin than you need and end up with layers of glass 'floating' within the resin, not as strong as a tight layup - in the real world I doubt that'll cause a failure, but don't quote me on that I'm still just a backyard hack. Should be able to find the 1:2 for not much more $$$.Not sure where you're located but Glue Products in West Palm Beach has some nice prices & good help.
