It's going to be far better to remove them and just replace with new metal roofing.
Thanks for the reply joe.
I've had good luck with panels that are 25 years old and no problems at all. These leaky ones are relatively new compared to others. I had guessed that they had been damaged upon installation when stepped on. Awfully easy to do.
I was hopefully planning on a spray can of sealer or maybe using a paint brush to brush on a thin coat of something that will seep into the hairline cracks.
There is a marine product that I've used to seal cracks in gelcoat. I assume that it is a very diluted
epoxy sealer. I'll need a good bit of it to coat a 3x12 panel.

At this point, I've got little to lose.
