first things first, paint a block of wood or something first haha. get the style down. Sweeping, 6 inches, etc... after that, its simple. Just tape off the area, lightly sand the handle with fine grit sand paper. wash the handle. Then just paint. super easy my freinds.
The handle won't stick. Its paint not epoxy haha. just spray and keep the coats light. thats really the key to spray painting any way. multiple light even coats. Dont worry, the handle is far to vigorously used for simple spray paint to seal it. Its all good
You will, however, eventually have peeling that you will have to touch up with a paint pen or something. Comes with the teritory though.
