Eastwood sells a great selection of coatings for metal. I use their Diamond clear for bare metal. Aerosol for small jobs like this and spray application for larger stuff.
Thanks. I will try some. I like the look of clean HR with mill scale and tried the rust oleum and other name brand hardware store varieties on it and they seem to scratch off so easily.
www.dxffiles.net claims it’s their original design and they sell it for $9. Small price to pay for a great design. They have several good designs for cheap.
