Full Body Paint, Worth It ??

If the manufacturer uses a high quality polyurethane paint for the full body paint, it requires nothing more than an occasional wash with a solution like Blue Coral water soluble wax. The paint already includes UV protection and continued hand or machine waxing just eventually wears off the layers of protecting clear coat paint.
If you have FBP, and the manufacturer used quality products, just wash it and keep your hand waxing materials in the garage. There is no need to do it and it only damages your paint in the long run.
