Hello Peter,

In the past I would use a cutting compound and a buffer to remove the
staining, not realising that the gelcoat itself is only a few
millimeters thick. If you cut it back regularly you will soon end up
with no gelcoat. My advice now is to use a company called GRPro-clean
who area able to remove staining and chalking without cutting back.
Well worth a try..

Good luck

Simon

Hello,

I've recently purchased a six year old 34ft jeanneau. Whilst
generally the boat is in very good shape I do have some fairly bad
yellow staining on the gelcoat topsides. Also there is a large amount
of chalking effect which is probably caused by the strong UV light in
Spain.
Does anyone know of a company/product that could remove the staining
and chalking without grinding??

Thanks Peter.
