clean them off with CIF then burnish with fiberglass burnishing paste Faclea G3 is a good one but make sure you remove the burnt on metal. I have been unfortunatly in this situation three times now once in Port St Louis where some german apent the winter grinding his metal hulk alongside my boat again in Gibraltar this time some shit from the UK living on a reck moored next to me and agian in the uk over wintering in Lancashire, the marina cleaned up this time as it was their fault. but make sure you remove the metal even pick them off with your finger nail or they will rust again. I havnt had any lasting damage but its a lot of hard work, hope it comes off OK. Perhaps you should approach the owner or the marina for their help.

Oxalic acid is the usual recommendation. For limited infestations the hull cleaner K9 does quite well.

I too have some rust spots on my Hurley 22 and would be interested to hear how you solve the problem. However the main reason for my post is to make sure you know about the Hurley newsgroup here

Oxalic acid will help remove the rust staining but you must remove all traces of the original iron contamination. If this has been caused by cutting mild steel close by, the very hot iron particles will have burnt their way partly into the gel coat and fused there. Same applies to grinding "sparks". I would recomment carefully and gently scraping the surface with a stainless steel scraper. You will feel the little "bumps" of iron as you scrape them off. once the surface feel smooth when you run your fingers over it then is the time for oxalic acid to remove any staining.

Wet the area down and leave overnoight and check again the following day for any more staining. Depending on how far the cutting was done from the plastic (GRP) you may be lucky and find the iron debris is all on the surface and easily scraped off.

Finally a good buff up and polish / wax and you are back in business

Re: smoke in cabin

The cockpit lockers lie between the lazarette and the bottom of the quarterberths and all should be completely separate apart from wiring/ gas pipe holes etc. I sometimes get an outboard smell in the cabin but would have thought that a significant amount of smoke was definitely cause for further investigation.

How old is she? - fin or bilge? Oxalic acid is the main ingredient in most of the "stain-removing" products such as Y10.

Not sure if you have seen this or not...

It works great on GRP and even on fabric too but only removes rust, not grease or anything else with little or no rubbing. Actually, rubbing doesn't make a huge difference - if the rust layer is thick it is best to apply a couple of times to eat through the the rust. I'll used it on the dinghy, tubes and GRP, and on vinyl fabric and linen cloth.

Hope this helps
