I agree on all points.  The caveat both me and Huw have mentioned needs to be 
observed:  In areas where strength is an issue use the standard Audi bolts.   
However, the vast majority of nuts and bolts on the car stainless is plenty 
strong for.  Example:  I've used stainless locknuts on the engine and 
transmission mounts as well as stainless hardware to secure the transmission 
mounts to the subframe.  No problems.  I would NOT however go using stainless 
on the bolts that go through the control arm bushings, the bolt that secures 
the ball joint, brake caliper support bolts,   things like that.

Hehe, oh yeah.  Have to agree that this is a big PITA.  I purchased a pair of 
extra long needle nose pliers just for this reason :-)
