I remember on the ones I have done that the holes were very tight on their own so I didn't use any sealant. Will they stay that tight in the future? My great grandchildren may be able to tell us once their parents and they have been born and and grow up old enough to drive. They will likely be teleporting by then and not know what a truck is.
