I've tried to do a small repair with epoxy and carbon tape, unfortunately it got rained on before it set and won't go off. I've taken the tape off and cleaned off as much epoxy as I can in order to start again, but I'm left with a sticky residue that won't dry but also won't come off. Is there anything I can use to clean it off (white spirit?) that won't then stop the new epoxy from sticking, or would I be OK to just put the new epoxy and tape over the sticky stuff and assume it will bond? ------------- RS600 1001 |

get some acetone if you can, and use this to carefully clean it off. You want to remove that uncured stuff, otherwise it will fail.

you need some epoxy thinners. that will get it off in a
jiffy. http://www.ecfibreglasssupplies.co.uk/store/durabuild- thinners-p-1212.html That stuff ^^. Its expensive so try and find someone who has some you can use before you contemplate buying it. ------------- |

Or, as I suggested, http://www.ecfibreglasssupplies.co.uk/store/-c-21_463.html - acetone Really. That, and Methyl Ethyl Ketone (which is in that thinner, but is harder to get hold of on its own) are the main things we use for cleaning the resin mixers at work. ------------- -_ Al |

At Hartleys we used to use Acetone for pretty much everything. I agree with Al!

Small amounts are available from model shops as MEK-PAK polystyrene cement. |

Thanks guys, I'll give the acetone a go I've just found this - same make as the epoxy I'm using so should work (I hope!) http://www.sailboats.co.uk/Catalogue~Blue_Gee_Acetone_Solvent_250ml~p_BG27003~c5193.html - http://www.sailboats.co.uk/Catalogue~Blue_Gee_Acetone_Solven t_250ml~p_BG27003~c5193.html ------------- RS600 1001 |

Small bottles of Acetone can be found in your local chemist.

Nail polish remover from tescos = acetone ------------- |

| Tescos may add nail conditioners/skin softener too though, so watch out! Doesn't seem to matter for cleaning glue off sails though. |

Mags is correct ! Usually nail varnish remover will contain things like lanolin - or other fatty compounds - otherwise you will de-grease your skin as well as removing the varnish. We used to make up a couple of litres in the lab on Friday afternoon. - One winchester quart of acetone, lump of lanolin, dash of methyl ethyl ketone... My colleage reckoned that girls would do almost anything for a 500ml bottle of nail varnish remover. At least, that's what he said One thing that I discovered was that uncured epoxy will prevent gelcoat (polyester resin) from ever hardening. Acetone worked for me... Colin (MR3387/Solo 3340) |

I did wonder about nail polish remover but I decided not to risk it as, like others have said, there is other stuff in there too. The Blue Gee acetone arrived this morning so I'll give it a whirl when I get back home. The boat is once more in the living room to avoid the chance of rain stopping play again. ------------- RS600 1001 |

Nail polish remover is cellulose thinners, isn't it? I've always had better results with genuine epoxy cleaners than acetone. West make one which Robbins Timber, amongst others, sells. ------------- Firefly 2324, Puffin 229, Minisail 3446 Mirror 70686 |
