Gradient-Brushed Steel Wall Art
Create abstract panels from scrap sheet steel. Use 40–60 grit to remove mill scale and define shapes, then 80–120 grit on the Type 29 edge to sweep in arcs for a gradient brushed effect. Torch-heat for color if desired and clear-coat. The conical Type 29 is great for blending flat sections and soft curves.
