This is my 3rd summer with the pool (2 winters). Could my filter gasket have already gone bad? It's leaking a lot from behind the band clamp. I took the gasket out, cleaned it, re-lubed it, re-set it. I always give it little whacks as I tighten it. It is my understanding that helps to set it properly. I can't see anything physically wrong with it. It's not dried up, or brittle at all. I have a replacement gasket on the way tomorrow, but since the current one looks fine to me, I'm doubtful that it will solve my problem. What else could it be?

The first step is to separate the halves, thoroughly clean both sealing surfaces, and check the o-ring for nicks or cracks. Then, re-lube the o-ring with silicone lubricant (like magic lube II) and reassemble. Ensure that you are evenly tightening the band clamp by lightly tapping around its perimeter with a rubber mallet while tighten the clamp bolt. If it still leaks then the next step is to change the o-ring.

That's been my process for the last 2 years. Both surfaces touching the o-ring were basically spotless when I was troubleshooting. I actually have that exact same lubricant - magic lube II. I guess I'll see what happens when I get the new o-ring tomorrow.
