Adhesive issues , so very different

What type of adhesive are you using? How do you apply the adhesive? What sort of material are you gluing together? Glass on Metal; Metal on Plastic; or Glass on Plastic?

For many different material I prefer two part epoxy which if you have clamps or something you can use to hold the two different materials together you can wait for the two part epoxy to dry. But if I do not have the time to hold the two materials together or the materials are hard to get to stick together I use Superglue specifically one with a brush applicator which is easier to make sure the glue is applied evenly.

If it is for a material that has high heat and has a constant pressure already holding the materials together like a Gasket joint I use RTV which will create a water proof seal and resist high heat. RTV is also good for keeping electronic wiring together "close" but separate for to maintain a plastic covering. You can also use a glue gun for this also but RTV has the High Heat protection that some circuits need.

I do not know if this answers any of your questions, but I hope it helps someone.
