I've thought about adding a clear bra. I have one on my sports car, and it works great.
But I haven't gone that way yet. Late this season, we did the ceramic coating (did it ourself), and it makes bugs much easier to get off.
Before we did the ceramic coating, we used this product from Amazon. It really is a true spray on, wash off solution, but I'm sure it can't be easy on the wax.
