This is for the Morse-Libby Mansion, National Landmark, which some of
you may have visited when here in Portland for APT2003. The iron
balusters of the perimeter fence were installed new about 7 years ago
and have not lead paint on them. After using the locally recommended
"mid-range" coatings the balusters are showing rust and need a more
effective coating. Thank you all for your insightful comments. I'll give
this more research and study.
