would you recommned using one of these to assist with the polishing or just hard workhttp://www.metalpolishingsupplies.co.uk ... ium-brass/
To be honest i used a number of different sanders/power tools but they were too harsh and just made a mess. i did use a small model drill with wire brushes but it flicked Nitromorse into my eye
Stick to a large and small paint brush to apply, a plastic and metal scraper, a bradall or sharp metal point and lots of different grades of wire wool. Gloves and goggles are recommened. The eye thing hurt like hell and could of blinded me.
