I worked for a Miller beer distributor, 2 years of washin trucks for them. 24 straight trucks and 2 to 4 semi's with trailers a day plus 8 salesmens cars, 6 days a week.
I got sick of washin the same things day after day.
Started out on my own in the summer of 1989,
I Went to Sparkle Hood and Vent cleaners school , in Joplin, MO in 1990
to learn Hood Cleaning,
Yes they offered certification way back then!
I also owned a Detailing Shop for a few years, But sold it due to lack of personal time, and felt I was burning the candle at both ends.
