Re: Best thing to clean bow rails and windshield frame?
i just read this in a post about building a windshield from scratch, heating the aluminum and bending. here's the blib on polishing afterwards.
When you have the shape you want, file any dings or scratches out and then wet sand with 400 grit and finish with 600 grit. If you have a bench grinder, you could put cotton buffing wheels on it and polish the moldings, or use metal polish by hand.
