[SEL] quick electrolysis question - cleaning galv parts

[Curt]

Bill,
Out of curiosity, what brand engine is this that has galvanized fins on 
it? Hot dip galvanizing is a lot of trouble to go to, especially if you 
have to go to the trouble to keep it out of cored cavities in a high 
volume production environment. It is galvanized and not just spray 
painted that color right?
If you have just a little rust on the edges, how about removing the gunk 
with some brush work and lacquer thinner. The use some Scotchbrite or 
steel wool to remove the light surface rust.

I gotta galvanized question for the group too. Had to make a new battery 
box top for Devin's engine a year ago as the original galvanized one was 
missing. It looks like bling on top of the 74 year old aged galvanized 
battery box. Has anyone experimented with artificially aging galvanized 
tin to make it look like an original?
