Nice work Bruce,
We'll see you out at Spring Fling with a display of your product.
Maybe think about a vertical board, elevated banner and EZ-up ( mostly to hold banner) to spruce up your booth. I still think you're a little under the radar. So many people are oblivious to stuff in a swap meet.
Maybe a physically exploded view wiper motor to catch people's eyes that you will restore their motor and just not sell restored ones. I remember one guy telling me he'd like to get a his motor to look like the ones that guys sells at the show. I'm like, "he'll restore yours too".
