Query: Good product, with 1 big issue

I really thought the price was right when I saw this. I needed a seal to keep the rain water out. It works great. One thing it includes is the glue with the gun to apply. The second we used the gun it broke. It looked rusted and old. That is unfortunate given the price I paid. Like I said, I thought the price was fair given everything included. I wish they would check the products before shipping. It would have 5 stars if everything worked.
