well technically i don't have a garage yet but Ive got more safety proceedures than i could possibly list being tuff could cost you big time!!!
the right tool for the job always . think the job all the way through (or as far as you can) organization and procedures will help (a place for every thing & every things in a place) time don't rush .
well i pretty much work alone because i have so many procedures but im not superman i cant to everything by my self (although i try to)
be safe & good luck
