Clean your surface with TSP and sand, if necessary. This allows the next layer of paint to stick effectively. Wipe away any sanding dust.
Rub a wax candle on the edges. A quick rub creates a barrier that prevents the spray paint from sticking in those spots. Give the tray two light coats of spray paint and set aside to dry for several hours.
Run the 100-grit sandpaper over the waxed edges to remove some paint here and there, giving an antique look.

Cover the tray with a coat of Mod Podge and let dry for a few hours.
