If you need to glue glass to metal then it is important to choose the right glue.
If you select a glue that is not suited to the task at hand then the repair job is going to be a disaster.
Here are a few quick questions you can ask yourself that will help.
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.
