My daughters gave me 2 white rockers for Mothers Day 2013. They purchased them assembled from a local CB.
After one year the rockers are covered with a black mold which is IMPOSSIBLE to remove without removing the paint. The mold is not only on the exposed sections but underneath as well.
I don't know what kind of paint was used but I do know a primer was never applied prior to painting as the paint flakes off when washing with water and a soft sponge. Not priming outdoor wood furniture is a real "no no".
