As you may have already discovered the hard way,though,paint doesn’t apply to metal well.But there’sa surprisingly easy step you can take to make sure the paint adheres evenly to the metal and doesn’t immediately chip off:Just dip the galvanized metal connector in plain vinegar or wipe it with a cloth soaked in vinegar.The vinegarremoves any oiliness and etches the surface sothe paint will adhere better. If you immerseyour connectorin vinegar,however,don’t leave it in there for more than a coupleofminutes orthe vinegarwill remove the galvanized coating.

Once it’s dry, it’s ready to paint. You’ll want to start with safety gear. Spraypainting is fairly safe, but it can still be toxic to breathe andtoskin or eyes. We recommend wearing safety goggles, glovesand a paint respirator mask with particulate filters.

After you’re geared up, it’s time to add the primer. Make sure you hold the primer can sixto eightinches away from the target connector. Once the connector is primed,wait at least 10 minutes for it to dry beforeyou beginpainting.

The first step for a solid paint job is to shake the rattlecan for two minutes before the first spray. After giving it the solid shake, test the nozzle on a cloth or piece of cardboard. This is especially important if you’ve let your spray paint sit unused for some time. The solvent can get backed up in the innerspray tube. If it comes out unmixed with the paint,it could cause the paint on the surface to run and create an uneven job while extending drying time.

Once you’re ready to spray,be sure to keep the can 10to 12inches away from the metal. Paint in a sweeping motion by starting the spray before the connector and releasing after the pass. You don’t want to finish on the connector.

You should apply at the least two coats of paint. To ensure an even application of the spray paint and prevent running,it’s best to wait one hour between applications.

If you don’t plan to use your spray paint in the near future,make sure you purge your cans! Turn the can upside downandhold the nozzle until the sprayturns clear. This is a great practice for preventing caps from clogging and extending the life of your paint cans.
