Can I seal this?
I posted this in the garden junk forum asking for opinions about the color I painted the base. Both pieces I obtained while junking and they seemed to go together for a nice mushroom for my garden. Almost all responses came back that I should not place the stained glass part in the outdoors. It was formerly a hanging light fixture, that I removed all the light parts from.It is extremely pretty but I have no place for it in my house as it is 21 1/2 " across at bottom. Is there anything that I can seal it with to help protect it from the elements? I don't want to get rid of it as I love it but not sure I want it to ruin either.
