While the Pam (spray canola cooking oil) worked well, there was an
unexpected after-effect: the oil seeped out of the channel and ran down
the side of the trailer, which combined with the road dust to produce a
truly ugly sight! After a few days, when the seepage stopped, 5 minutes
with a foam brush at a car wash cleaned it all off.
