I'm famaliar with that with that logic - I have three sons (21, 19, and 16 years old).
An hour or two washing and polishing yields immediate results. My older two can find a prime spot on the college campus and take their shirs off and be able to impress the co-eds by showing off their cool car, their cranked up stereo, and the results of a lifetime of weightlifting all at the same time!!
Oh, to be young again!!
But an hour on their backs in the parking lot changing oil doesn't seem to invite the same attention from the girls!
