Well perhaps that's the normal way in America but it never has been 
in Europe.  First you have to make the hole and then you have to wipe 
off the exuded glue and you're still left with a pinhole.  I don't 
see the point.  With the European method the glue escapes and joins 
the glue under the hammer which is going to stay there and that's 
that.
