Yes, the Raptor is meant to get dirty, but I would say it looks best when clean.
You should clean it regularly using quality products and good technique, to prevent damage. And since it is so much fun to get it dirty, it is very helpful to have a layer of protection on the paint and other exterior surfaces to protect from damage and also to make cleaning easier and faster.
Paint Sealant is a great option for the paint, and lasts about 6 months with proper washing. Some
VRT will protect trim and vinyl. To protect everything on the exterior (other than tires), the
H2O Guard & Gloss is a great option, and lasts 1-2 months.
