Just remember not to use a wire brush on it...or ever let it get empty. An empty gunite pool can "float" out of the ground, but not if there's no ground water. If you let a vinyl pool go dry the odds are you'll have replace the liner.

About every 5 years or so hard-sided pools seem to need serious maintenance, like re-surfacing or painting. A well-maintained vinyl pool can go 10-20 years without replacement, though at 10 you may need to think about a liner.
