Having worked for several years developing soldering processes I have to say "DON'T PUT SOLDER ON YOUR HARP REEDS." Lead and silver are nasty and the effect is cumulative (stop it Madcat, I think you're the only other Huang advocate on here :), so you may not notice anything now, but your kids will notice later.

P.S. Maybe you can use that special tape Doug used to windproof his harmonica.
