I have just painted a windowsill in Dulux Once satinwood. It looks like a gloss and I don't like it so am going to paint over it. I have remembered, belatedly, that I've heard that oil-based paint can go yellow. This was certainly the case with oil-based paint in the past. Does anyone know whether newer oil-based paints also go yellow?
If they don't, then I can paint over this with an oil-based eggshell paint. If they do, then I'd prefer to use a water-based paint. The problem is that apparently you can't put water-based paint on oil-based paint, as it won't go on properly. If I sand the windowsill first, would it be ok? Or would I need to completely remove all the oil-based paint, which I imagine would probably be difficult?!
Thanks so much for any advice!!
