I've got some ceiling paint that started peeling in front of the oven
(which vents into the kitchen -- just a simple household range) not
much more than 5 years after being painted last. Not sure what kind
of paint it was -- I wasn't around at the time. I'd like to do the
best I can to delay this from happening next time -- what sort of
paint would resist the heat the best? What else could I do to help?

Thanks!
