What are you going to do about tin whiskers[1] showing up in electronics? How will you get lead soldered electronics that don't grow tin whiskers and short randomly now that the EU has banned lead solder in new products? Are you going to use electronics from before 2006 when the RoHS legislation came into effect? Is anyone making consumer electronics with everything nickel plated for durability despite the cost and weight issues?

I'd need to do some research to see if reflowing the solder would fix a low level of tin whiskers. Usually, the flux effectively increases the surface tension of the solder, causing it to form nicely around the pads and contacts. So it isn't clear to me how well the reflow will work without additional flux.
