No it's not the rising price of fuel!
I tried using an aid to help me paint fences today, it was a spray system that involved pumps and air pressure and a long dangling tube, which was mostly unattractive and gangly.
It did not help the process of painting the fence, and therefore hindered it and prolonged the already mundane experience. Blocked tubes, low pressure, paint on the rockery. It did not go well. The cleaning process took far too long and a simple answer to a simple problem was proofed stressful and far worse off that the original hard grinding work.
You cant cheat the work!
