QuickCast Pattern Leak Testing Methods

What methods/equipment/techniques are available (and tested) to check
QuickCastTM patterns for leaks? I have found a smoke machine at
"www.thesmokemachine.com/homepage.html" that has been developed for the
automotive industry to find vacuum leaks. Has anyone ever used one of these
for testing QuickCastTM patterns? Does the non-toxic, (vegetable?) oil based
smoke cause the QuickCastTM parts to soften or swell? Are there any foundry
related problems associated with it's use? ....etc.....etc.....

Any help would be greatly appreciated. Thanks.
