We’ve all stored nails in old coffee cans and used a piece of masking tape taped to the outside of the can to record the type and size of nail. Here’s a better and more permanent labeling method. Spray a stripe of white appliance paint across the outside face of each coffee can. When it dries, write the nail specs on the paint with a permanent marker. Appliance paint has a tough, gloss ﬁnish so it doesn’t chip easily.
