Coffee cans make geat second hands
To finish both sides of a project at one sitting, I support it on empty coffee cans fitted with sheet-metal screws that protrude from the bottoms as shown above. Simply poke holes in the can bottom, then drive the screws through the holes from the inside of the coffee can. After coating one side of the project, I turn it over and rest it on the screw points to complete the job. Although the screw marks seldom show, coating the "best" side last ensures a mark-free job.
