Ok,yeah i see what you meant now.I was thinking of the 2 part epoxy that a lot of people use in wood working projects,not so much as a finish,but more for filling voids in the wood,etc.,but i have seen it used a finish on some projects.For this purpose though,as far as adhesive,at least for me,i like the idea of the double sided adhesive,that way if i want to change it later,it would be pretty easy to remove.
Yeah,i make a lot of pens,and almost always use the super glue finish,even on stabilized wood,since it serves 2 purposes.The super glue gives good protection against stains and fading,as well as being able to be buffed to a very high gloss.I had first thought of maybe trying that finish on the veneer,but i don't think it would work too well here because the glue finish is fairly fragile,and i don't think it would be able to conform to the curve of the door without cracking,in which it could be applied after the wood is in place on the door,but then that brings it back to ease of removal later,since the glue would seep down around the edges,essentially gluing it to the door.
Another option for someone who wanted to do this would be some wax.I use Johnson's paste wax from Lowes on some of my projects,and it doesn't really aid in durability,but does seem to help keep the wood from getting stained if something gets on it.
The stabilizing resin i use is called Cactus
juice,when i was buying the supplies,it was the most highly recommended,so i went with that.
