My pool steps have been developing bubbles over the past 3-4 years. They appear to be surface bubbles. I am told that those are not an issue (except aesthetics), and they should be fine since there is fiberglass underneath.

Does that seem correct?

I am getting ready to put in a new liner. If I put one in, and need to replace the steps in the near future, I'll have to pay for a new liner all over again.
