This fast-drying, water based paint has certainly impressed our projects and workshops teams. The satin-matt finish is particularly close to that of Doughty Clamps, and would blend in well. Excellent adherence to zinc, aluminium, copper, and brass, making it ideal for overcoating aluminium and steel trusses and beams. The finish is resistant to scuffs and will keep scenery and truss rigs looking smart. It will also provide strong anti corrosive protection. We’ve tried it out by brushing on to aluminium tube with, and without, preparation work and have been impressed by results. We think it would also spray well. 2 coats recommended.
