Went around to a house the other day as a favour.
He is having this problem where eff. is appearing on the fiberglass walls of his pool. Upon inspection I wasn't sure if it was in fact eff or not. Seemed to flake away and wasn't a powder type substance. I know I am being vague but as mentioned doing this as a last resort type of thing.
Attached are some photo's of the affected area (top two) as well as a short video. Anyone shed any light at all?
Cheers,
Jarrod
