Poke a hole in the POR lid? That is a different approach. I have always covered the open can with 2 layers of Saran wrap and refit the lid. During the humid summer months I have also filled the space above the paint with Argon from my welder to displace the damp air. No matter what you do, the shelf life of POR is "officially" only about 6 months, less once opened. That's why I only buy it in the small "6-pack" half-pint cans.
After buying my initial sample kit from POR, I have only used "generic" prep chemicals. Both their Marine Clean and Metal Ready are rather expensive. I typically use "ZEP" cleaner from Home Depot and a generic phosphoric acid (Right Stuff) from a local agricultural supply store. As with all painting, the prep work determines the outcome and so far I've had excellent results with the generic chemicals.
Back on the original topic of this thread. If the tank appears silly thin then by all means get a new one. Your peace of mind is equally important as stopping a leak.
