Hi all,
It looks like I'm shortly to buy an older GRP boat that could do with a little love. Where fittings have been attached to the hull (block eyes, self bailers etc) there's nasty rust marking... I'll try and attach a picture to show.
I'm assuming that I should replace all the fixings with stainless versions, but how can I get rid of the staining? Is there a way, or do I just slap on some white International?
Thanks in advance

Re: Rust marks...
Stainless isn't utterly corrosion proof if you leave a boat wet and salty enough. I'm not sure that all, maybe any of those are not stainless. It's usually painfully obvious if there's mild steel fastenings. T cut and wire wool may well help with surface staining.
Re: Rust marks...
once you get the fittings off have a go a the gel coat with a Magic Sponge. I've found them invaluable in recent months for cars, covers, boats and boards. I had to buy 100 off eBay after being caught 'borrowing' them from the kitchen

Re: Rust marks...
Any Oxalic acid based gelcoat cleaner will get the rust off both the stainless and the GRP. Its best to go for the gel type rather than powder as you don't want any abrasives. Heavy rust stains will require repeated applications. Use any good brand of metal polish on the stainless and GRP polish on the gelcoat after you've got the rust off.

Agree with above. Stain devils (rust remover) is Oxalic acid & did a good job on my sails. You do need to leave it on for a while though, and maybe a few applications.

Great stuff - thanks everyone

I tried the rust stain devil on cotton sails and it ruined them so I had to stitch a patch in !
