Troy,

there are no special precautions to be taken when exposing IR films
trough WA lenses. WA lenses actually make things a bit easier: 1. They
allow you to handhold your camera even when using relatively long
exposure times - even for a strong coffee-drinker like me, 1/30s to
1/20s is still possible ;-). 2. WA lenses generally offer a
comparatively large depth of field. This means you don't have to bother
with IR focus corrections, which might become necessary for visually
opaque filters in combination with tele-/ macrolenses. 

Happy photographing,

Eckhard
