Painting v Oxalic acid

[Marine Reflections]

I notice a couple of threads on use of Oxalic acid, to clean/renew a faded/stained hull.

Should this fail, apart from going to a yard to get it done professionally, what would forumites recommend for a simple hull 'paint' job. Someone I know, with little previous experience of maintaining a boat, has been quoted over £600 by a local yard (+ materials), for painting the hull of his 22' boat (which was built in 70's & not of great financial value). I remember some guys successfully painting their racing dingies, with 'Woolworth' paint, so is there a viable alternative to the 'marine' products,to paint GRP?

Oxalic will only clean stains, it certainly won't 'renew' a faded hull.

That said, I agree with others, painting is miles away from being the next option.

Wet sanding will be the answer.
