I was thinking about this as I dinged my head on my garage door opener for the 3rd time as I was trying to buff the sealant off of the roof of my truck. What would be the harm if I applied my sealant like usual, but just left it there on the roof of my truck instead of buffing it off? Obviously it would look bad, but in the case of my truck, it's over 6'-3" high, and all I really care about on the roof is the protection it provides(Besides nobody can see it). It seems to me like it would provide more protection as it would be quite a thick layer of sealant compared to what's left after buffing? Am I wrong?
