The duplicolor undercoating in a can is so far one of the best undercoats I have used that you can buy from a can. It sprays on evenly, doesn't clog the tip or make a huge mess like the rubberized spray liners. It dries quickly and will stick to lightly prepped galvanized as well as steel. The undercoating sprayed on well and dried well, the color is not exactly black like they say, it's a very dark brown that's almost black, but no huge complaints about the product overall, it can be a bit runny on application so I suggest a well prepped surface, and light coats to prevent runs. I would recommend this undercoating to someone looking for one.
