I was pretty intimidated at first too. And I don’t pretend to be an expert, but there is something therapeutic in being able to wash a car well. I think it’s a level of detail that is analogous to why we like high level finishing on movements—there’s a technique to being able to do it well and it extends beyond the parameters that most people consider as “good enough.” I’m happy to share some resources with you if you would like to PM me. Some of it will probably end up referring to specific brands and retailers, so I’d prefer to keep it off this forum.
Thanks,
Brian
