I don't live where there's a lot humidity like Florida, but suggest
that you might want to do the following:
1) Get a dehumidfier for the garage.
2) Work at keeping rust at bay. Use floor wax (no silicone) on
chisels, etc. to prevent them from getting rust. I'd imagine you
will have to
this on a regular basis, like weekly.
3) Look for Boshield at a Rockler, Woodcraft (I think Lowes might carry
a rust inhibitor. Instructions on the product.
Good luck. Also do a Google search in this newsgroup for terms like
"Florida", etc. A lot of woodworkers are in Florida.
Oh, find a class or a club near by. Ask the members what they would do.
