Paint protection when installing the engine

Thanks to John Prusnek on the old Yahoo! Loopframe_Guzzi news group (which has now moved to Groups.io) for suggesting this idea.
When installing or removing the engine from the frame, it is all too easy to scratch the frame in the process. Taping the frame doesn't seem to help much and the foam plumbing pipe insulators are simply too thick to work on the bottom frame tubes. Instead, thin walled plastic tubing is a great solution. This type of tubing is commonly available to cover shower curtain rods.
