I don't know if this stuff has been discussed here or not. Lately there have been a few infomercials about this stuff, or similar, and it looked like there may have been modeling applications. I picked up some At Bed, Bath and Beyond to do a couple of tests.
The sprue gates for the Stearman I am working on are on the large side and I didn't do a very good job getting them off. there were 2 that lined about the there was a sort of pitted surface after a light sanding. A drop of the liquid glue and 20 seconds with the UV light and it was hard. The product said 8-10 seconds but it's not enough, at least with this brand. Sanded out great, really smooth.
Then I starting thinking about PE and how strong the bond would be on a small footprint. A tiny piece of fret was bent 90 degrees and bonded to the inside the Stearman wing. The pre-cured glue is just viscous enough to hold the part standing on its own. Something being bonded to a vertical surface will likely need to be held unless it's really small. After curing it holds the full weight of the wing upper half with a pretty uneven weight distribution putting some good torsional stress. Looks darn strong to me.
