Kung Fu, I agree soo much. When I got the 1975 Datsun 280 Z back in 2003, it had been in So. Cal it's
whole life. During the restore, never had to use penetrating oil on anything !! Even the exhaust manifold/
headpipe bolts on the 28 yr old exhaust came off.
Now, up here in the Salt/Rust belt.....sawsall use is mandatory equipment .
