> Thank you for correcting my mistake. I got aluminum and stainless steel confused. 
Not being in the mechanical department, but the operating 
department I do make these mistakes sometimes. I have seen 
cars on the RIP Track with the sides removed the the steel framing 
being reduced to about 1/2 its orgianal thickness due to corression 
from the traped moisture. Sure is amazing how much steel is 
rusted away.
