Is glue-gun glue waterproof?

I have never used a glue gun. I have an Iron-on patch that I would like to affix to a quilted denim jacket. I don't really trust the glue of the patch to hold so I thought I would use a glue-gun.
Does anyone think it will survive in Seattle rain?
Also, do you think that it will work better if I use the glue gun plus the iron-on patch glue?
Thanks.
