If I were paying someone to fix em and he/they got a quality product out in a timely matter,
I would not care what the shop looked like.
Myself on the other hand, I`m just glad to have a concrete floor. A roof and a locking door(s). Oil stains are just a reminder.
I`ve not seen your shop OL 55 but me thinks you gotta make a mess in the kitchen to make something good.
