I have bits of carpet in my garage beside the house where I keep and work on most of my motorbikes, as it’s easier on the knees and it is stopping any oil getting into the concrete floor before I get a chance to paint it.
The farm shed (old chicken shed) I rent for keeping and working on my cars couldn’t have carpet in there at the moment as its so damp but I have just painted the walls to brighten it up a bit and the floor to seal it, has taken me weeks with all the shit I have had to move about to get a bit done at a time, but I finished it yesterday so now its time to sort out what is going where and bin the rest
