That depends on the materials used in its construction. Wooden hot-tubs that I have built and worked on do not require paint or fiberglass. When constructed, water soaks into the wood and swells to prevent leakage. These generally hold-up for ten years or more (depending on the materials used) and are usually simple to repair or replace rotting boards.

Fiberglass hot tubs can get rather ugly before owners are ready to trash or repair their spa. For this dry it, remove all pumps, seals and screws. Lightly sand the exposed surface to prep for paint and repair any cracks or seem-leaks with equivalent or better seals and rust-proof hardware, pumps and jets. Use fiberglass cloth, fiberglass tape and fiberglass paint to complete the job. Up-grade if you can.
