What types of glue or epoxy do you use? What works well with what? and what has bin a total disaster?. And most importantly what holds up and doesn't turn yellow over time? I pulled a few kits and some locomotives out that have bin stored for a few years and well I guess I must have used the wrong glue on some of them. The # boards had come loose and the windows had turned yellow where the glue was on a (MTL F7) And some of the bldg kits that looked grate when packed away now have yellow spots and/or are deformed or have come apart.. I don't know what glue I used but I don't want to destroy anything else by using the wrong stuff again. So What is a good Glue or Epoxy to use for Wood ? Plastic ? Styre ? Brass ? foam ? Resin ? other ?
