I brought 3 lovely black zinc rectangular planters last year which are on my deck with bamboo in them - I was really pleased with them to start with. But this spring I noticed the black 'paint' flaking and peeling off and it's getting worse. They weren't cheap and I'm miffed as to why this has happened. I can't find any answers online and I emailed the company I brought them from but they haven't replied.
Has anyone else experienced this or is it just me? I'm reluctant to buy any more
