I have a divingboard that needs a make over. I assume it’s been with the pool since 1979. Is fiberglass and it has two small hairline cracks. Also, the paint (or what ever that is on the surface that looks like paint) is chipped.

Leslie’s Pool Supply sales a kit to repair and paint the divingboard. I wonder if you have use it and what do u recommend. I power wash it today but most of the painted chips are still attached to the board and would need to be removed. I there any solvent that would help me to easily remove the chipped paint? I know sanding would not be a good idea since the board needs the roughness to prevent slips.
Thank you for your knowledge and time
