I aim my flash up about 45 degrees and then use a little extension on the flash that redirects some of the light back down. It is supposed to be used to put catchlights in the eyes of portrait subjects, but it works great to eliminate glare in tank shots.
Almost all of the pics used the flash to some degree.
