I just sanded down an old frame I am bery attached to, with with aims at re-painting it. However, I have fallen in love with the bare steel and just want to lay down a think clear coat. I don't have the money or the want for a clear power coat and I want to have a finish with low or no gloss. What would be best to seal it with? Also, I'm cheap and don't want to spend more than $30 on it. There are obvious options like clear spray paint but I want to do better than that. Clear oil-based laquer was a thought. If anyone has a better idea thanks.
