Nobody on this thread said anything about sealing the edges to prevent splitting. In my opinion it does help keep the chassis from de-laminating in small crashes, but that's not why I seal the edges. Some guys just like to make their car builds look good and are not always in a rush to get the car on the track. I doubt that the blue on the edges of Buckaroo's 10R5 make it stronger or faster but it sure looks nice
