Good job with the shop Steve. I would add is patio blocks under the outside covering. A couple inches higher than graded maybe with drainage underneath. Some rubber shop floor mats would be nice too. Love the work you are doing on the GoldWing!
Pavers would be nice. It was meant as a work area out of the sun. Been planning on taking in bikes as a way to make money in my spare time. (Have lots of it now) The Wing more or less fell into my lap. Maybe I should build another building for storage. Like they say, "Build it and they will come." Nature abhors a void.
Working in the shop in the rain and between showers. It's also a base for other things as well. Best $300 I ever spent.
Add $150 for the shade cover to work on things outside plus the shed will keep me busy through the summer.
