When I bring my jeep to the garage for an oil change, I don't need to remind them to use a copper washer around the drain plug or to remember to tighten the new filter. So if I drive down the road and oil spills everywhere is that my fault?
With this attitude, I would be leery to send you work. Just saying.
Well you don't have to worry, I no longer refinish, period. I have done enough of that over my lifetime. I did a lot of restoration and keeping flats -flat, round holes - round and sharp stamping - sharp was important and quite time consuming. I don't do oil changes either. Just saying.
