Hey, folks. Thanks for your replies on this.
I wonder if the impression was given I wanted to glue something up permanently this way. Not so. Am working up a little project to finish bright, more a 2 foot boat than the 10 foot ones I'm used to doing, and have been considering ways to avoid blemishes, pencil marks preserved under epoxy, too many dings or holes etc.
It was interesting to google this up a little, Like anything ya buy these days, there are many details and options to consider. The prominent hot melt glues are polyurethanes. There is a variety of formulations for different materials. They're said to clean up best with isopropyl alcohol or acetone. LocTite has a version claimed to be just right for wood, having lots of tooth into the grain, but I wonder if that makes it harder to clean off.
The downside seems to be expense. It is easy to spend $150 for a gun and shots of glue are often $13.50, though a dedicated bargain hunter could probably do better than that.
Why not wire, indeed? Or just duct tape.
