What happens here

As a daily maintenance tip, after each paint job and after the sprayer is cleaned, spray the entire gun thoroughly with WD-40. The WD-40 will work its way down inside the rails and threads of the gun, preventing paint from gumming up. This practice ensures that the gun remains clean and operates smoothly, and it allows for easy disassembly when future maintenance or a rebuild is required. Implementing this tip can significantly extend the time between full gun rebuilds, potentially allowing the gun to last two to three years without needing extensive servicing.

Goal: Prevent paint buildup and ensure smooth operation of the gun

Chris. One tip with the contractor 2 gun is what we do is every single day after after we're spraying, when the sprayer is all cleaned up, we actually spray our whole gun with WD40. And the WD40 works its way down inside these rails and it keeps the the paint from gumming up the rails and keeps the the gun working smoothly. We'll spray it down inside here. Spray the the threads. Paint won't stick to the threads and it's always it just comes right off. So at the end of the day, we spray the whole gun with WD40. Very good tip. And once when we started doing that with our guns, our guns will go two three years without having to take them apart and service
