When I was a junior in high school diesel mechanics, the teacher told us when you work under the hood of a car and do, say a plug or filter change, wipe off the valve covers and air cleaner lid.I have seen your cars, garage and workshop. You definitely know how to keep and make stuff look new. All my stuff runs fine, but maybe I'll bring it over for maintenance just to get it back clean <grin>
That way the owner knows someone actually did do something! I guess I took that to heart.
Such an impressionable yute!
