Restoration Blunders Backing Parts
Never Media Blast Alloy Metal Parts
John Murphy has spent the last 30 years dabbling in classic Mustangs. He's an amateur restorer who is home garage trained at the University of Hard Knocks. Yet he will tell you he's had a ball along the way. He speaks from experience when he says, "Never sandblast or even glass-bead an alloy part that had a smooth finish to begin with. This includes fuel pumps, Thermactor smog pumps, carburetors, distributors, cast aluminum power steering pump brackets-any part that was cast with a smooth surface." John tells us that although the part will be clean, you will never have the correct factory surface again. Use a vibratory cleaner, John adds, or a parts tumbler to massage cast parts to like-new condition. View Related Article
