Gelcoat staining
 

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.

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

The chalking you can get rid of by buffing with 3m's brown buffing compound,
followed by their white clear coat polish. I don't know if that will get rid
of the staining, but if it doesn't, you can try FSR. It's a blue gel with
oxalic acid that I've used to remove stains from fiberglass, even the brown
crud that builds up in exhaust tubes. Be sure to follow up with a good wax,
like Collinite fleetwax paste.

First: What did the stain come off of? It will continue to stain until
you replace the cheap fastner or whatever that is causing the problem.

stain...
oxylic acid or brandnames using it

chalking...
"fine" (or "super fine" - go for the finest they have) rubbing compound
from the auto supply store; use a buffer machine or your arms'll fall
off before you're done.

But buff only enough to get a good finish - you can go through the gel
coat if you try hard enough. Do it for a few seconds only in a small
area, wipe clean to check your finish, and buff again and check, until
you get some idea how much buffing is needed to get your finish. Then
you can do the rest of it with some confidence. Waxing after is a good
idea if you've got any ambition left.
