The powder coating on my belly clamp is peeling away. Time to buy a new one? What could be causing it to corrode like this? Is this normal wear & tear or something else?

That is certainly weird ... you don't happen to store muriatic acid near the filter do you?

This one time, at band clamp...

In April 2009, Hayward introduced the cast aluminum band clamp part number DEX2421JKIT.

Most of the time, aluminum is fairly corrosion resistant. However, sometimes it begins to corrode and when it does it can really get bad.

I would suggest sanding and painting it to reduce further corrosion.

If you plan on painting it you will need to use an aluminum etching primer for your top coat to stick. Aluminum is notorious for being hard to get paint to stick.

Cheap cast parts like that can be prone to that type of corrosion due to impurities in the casting.
