revamping wall light covers

If it doesn't work, I've just discovered a new paint range called 'French Chic'. They do something called Frensheen, in silver, copper and gold - I think. There is a Facebook page and the results of painted furniture/kitchens/PVC front doors are remarkable!

I've not had any experience of this but... since you'd have to sand it right down anyway if this doesn't work, I'd be inclined to sand the run so that it is level with the rest, then lightly sand the whole thing just to give the new coat of paint something to key into.

If it looks awful, then it will be a case of sanding or paintstripper! Good luck.
