- Since I am happy with the look of the raw steel after applying heat to the back from heating/ welding, and I will not be powder coating it over the top as it will be a too large piece of metal to easily transport to a powder-coating company, I started researching how to keep the mild steel from rusting.
- Penetrol. This is an additive for oil paint it's supposed to remove brush marks and increase the working time of the paint. It also works well to set metal to stop it from rusting.
- Clear acrylic spray paint is much weaker and chips too easily, which is why I'd rather not use any spray paints.
Video of applying Penetrol
- polish steel / rub off dirt before applying
- 24 hours touch dry, a week to fully set.
- Penetrol not available in Uk but after further research I found Owatrol oil which is the exact same thing.

- I will order a sample and see how it works with the welded/ distorted sheet of mild steel.
Testing Polish on Metal:
- I coated the left half of the sample sheet of mild steel using autosol polish. This didn't do much apart from remove the colourful tones. Instead polishing it would bring it back to its raw grey state if I kept going. This is not what I wanted.
Testing Oil Varnish on Metal
- Testing two patches with the 'Owatrol oil' sample that I ordered. I will have to wait until this dries and then reapply. This should stop any further corrosion to the finished look of the steel and may even add a gloss.
