Hi, I was wondering if you could advise me on what product I should use for a possible work scope I have coming up. The scope is to paint the external steelwork at a bus station, this includes the yellow bumpers and supporting steelwork for a canopy. All existing coatings will be removed using sanders and needle guns. I was thinking about giving it 3 coats of Sigmafast 205 LT. Any advice would be greatly appreciated. Thanks Steven
