FYI - Origins of Mud Guards

I have given some thought to the use of the word mudguard.  It seems that the British have adopted the word to describe and item that guards mud.  Since we in the U.S. don’t have that much mud to guard and we rebel against its accumulation we tend to fend it off if it attempts to become a part of our vehicle.  We, therefore, have adopted the word “fender” to describe this item.  I thought you might be curious.

Paint Codes

Red: 1984-1994 Suzuki Car (Saint Germain Red) 15P 99L-25797
Orange: Nason by DuPont 400-80/471-80 tm
Blue: Martin Senour Paint 49005

The following 3 colors are an inexpensive form of paint.  They each duplicate the color exactly and one can will paint a frame.  Follow the instructions.  Use a dust free area.  It takes a bit more time to apply but it is very durable and resists rock chips well.

Silver: Dupli-Color Engine Paint Clear Cast Aluminum DE1650
Black: Dupli-Color  Engine Paint Gloss Black DE1613

White: Dupli-Color Engine Paint Universal white DE1602
