I'd not worry about it then., just prepare as normal. Don't forget
that white paint yellows a bit anyway with exposure to light.

Many thanks to Chris, Dave and Huge for their help -- that gives me
confidence to go ahead and repaint without wearing my fingers to the
bone sanding!

Pity, though, that others decided not to answer my question, but to use
the the thread to declaim about the evils smoking. I had noticed!

That's the problem with usenet - people get side-tracked and begin
interesting conversations;-)
