Ducati paint is very soft.... which means less-than-precise washing/drying methods will end up putting micro-scratches into the surface... (aka swirl marks, spider webs). These microscopic scratches, over time, will reduce the reflectivity (ultimate factor in gloss) of the surface because they cause reflected light to disperse among the texture.
If you are serious about having a shiny Ducati, the first thing to do is to invest in high quality washing gear and research two-bucket method washing. Also get some high-quality microfiber towels for drying.
Next, you will want to remove as many of these microscopic scratches from the painted surface as possible, creating a new level surface for the light to reflect directly off of. With modern random orbital polishing systems, it is pretty easy for the DYI guy to do it. It will make the biggest difference in the overall appearance, gloss, shine (or whatever word you want to apply) in the paint.
Once the paint is level, it will reflect maximum light directly.
Then you can add a wax, sealant, or coating for (perhaps) a little extra shine and protection.
Here is a video I shot showing the newest tool our company produces on my Panigale Tricolore.
