How do you fix a bathtub that is peeling?

To fix a peeling bathtub, first, clean the affected area thoroughly with a non-abrasive cleaner to remove dirt and soap scum. Then, gently sand the peeling spots with fine-grit sandpaper to create a smooth surface. Apply a bathtub refinishing kit or epoxy paint according to the manufacturer's instructions, ensuring even coverage. Allow it to cure fully before using the tub again for best results.
