Well, what I think Van's doesn't want you to do is smear it all over when you're just trying to get it in between the parts. These pictures show how to add additional, after-the-fact sealant. Note that here, the rivets are installed. What these show is how to cover the seams where fuel could leak. Now fuel might not; your original sealant might have been perfect, but these are still the paths fuel could follow if you did not originally achieve a good seal. Block them and the fuel won't leak.
