If you need to glue glass to metal then it is important to make the right choice about the glue that you use.
If you select a glue that is not suited to the task at hand then the repair job may end up in failure.
Is it a short term or longer term repair?
If it is just a household item that you are looking for a quick fix on, most times a super glue will do the job.
