I have a 3-foot round wall "sculpture" made, I supspect, out of tin. My plan is to put it outside on the front of my house. Before I do that, I want to protect it somehow from the rain, so it won't rust and so that I won't have rusty stains dripping down from the sculpture.
Does anyone have any ideas for what I can use to coat the sculpture so that it will be completely protected from the rain?
I was thinking of some sort of clear, spray-on coating.
Suggestions?
Thanks in advance,
