Greetings,
So that's explains the heading 'mmmmkay?'. :-P Gosh! Had the same experience trying to mend a leaky water tank. I had to use epoxy sealant to do it. It comes with a thin aluminum sheet to place the two components together. Before I sealed the hole, there was some paint that I need to scrape off. Some were hard to come off. I cut myself with it. Careless of me too. Lesson learned and charge to experience.
Regards,
