Nitromors shouldn't bother the metal, u can use it on woodwork and its fine, its wot i used to use in the bodyshop i worked at. best way to do it is blather it (in a well ventilated place or you mite start to feel a bit squiffy :s ) cover it in a plastic sheet and leave it for 5mins, then come back to it with a paint scraper. Repeat as many times as u like, just remember to wash it off wi plenty of water, that should neutralise it. U mite wanna wear gauntlets too, coz if you get it on you and don't wash it straight off, it burns like hell!!! I used it recently on a truck cab I bought that was painted with enamel and it was fine, but don't forget when you paint it again to use a decent etch primer on the bare metal (not the ****e you get from halfords, same goes for hi-build, ur better off using proper stuff that you mix rather than the aerosols. I went thru four cans on a series 3 wing, and the whole lot rubbed off with wet and dry paper!!! If you don't have a gun and a compressor, put ur hi-build on with a roller and be prepared for a lot of sanding!) have fun!!!
