I got lucky with the foster parents.
My foster dad's brother used to take his Camaro apart once every two years, lube and recoat anything that was looking a bit faded or rusty.
I got to help teardown the engine completely, remove head lights, tail lights, shocks, brackets ect.....
It got me interested in mechanics, the other thing was that my foster dad did everything! I mean he was a carpenter, mechanic, welder, painter, raised animals, was a dog breeder and a radio operator.
It seemed to me there wasn't anything that he couldn't do.... well except school work.... he couldn't help me to do that
