A professional exterior painting expert will use a spray application for a smooth factory like finish. Paint from a bucket with 2 or 3 in. Also avoid caulking tongue and groove siding boards together. Lp siding products also come in sheets in when water runs down the face of the siding it tends to hang on the bottom edge wicking up and causing the bottom edges to swell and delaminate.

Then brush with the grain of the wood to smooth the paint. The most vulnerable profile is the lap siding where water can cling to the drip edge and wick into the bottom edge of the siding as shown in the photo below. The bottom edge of lp lap siding is where the failure is first evident. While paint does tend to somewhat glue these pieces together caulking them is never advised and can cause permanent damage.

Bottom of siding boards should not be caulked water is meant to exit through the bottom of each board. Once water starts to penetrate the drip edge the siding saturates swells and delaminates. Of paint in the bottom rather than a full can of paint.
