Rubberised coating removal
We have some Kef speakers (cast alloy construction) that had that silky
rubber coating. Needless to say this coating is a ghastly sticky mess. Were using acetone at present but wondering if theres a better solvent to remove this horrid stuff. Not too worried if it removes the underlying paint as some has come off already. Wondering about petrol but not the nicest stuff to work with... Tim -- Please don't feed the trolls |

It is a surprisingly good solvent for degraded tacky rubbery plastics. Wear suitably thick impervious gloves. -- Regards, Martin Brown |

One point raised was that no matter what solvent you use, the sticky goo will come through again in a matter of weeks/months. Is there any Fablon-like adhesive vinyl material which you could use to permanently cover the sticky surface and wouldn't look too bad? Loads on ebay, but I've no idea whether or not it is any good. -- Jeff |

I had assumed you were just trying to remove the sticky mess which leaches out of the rubber stuff rather than the whole coat.

There have been a lot of threads on this stuff in various groups recently
and I've not seen any consensus on what to do. If it is just a coating then it probably does have a solvent if you can identify what the paint is. I would however suggest that also you check up on the speaker units surrounds cones and suspension, as many speakers of a similar age seem to be almost write offs due to the plastic going hard, or falling to bits. Also be aware that if you create any dust from removal of the coating its going to be bad news for speakers. Brian -- ----- -- This newsgroup posting comes to you directly from...
