The TIX products are excellent. The TIX product enabled the repair without taking the hardness out of the steel, which would have happened if a higher melting point product had been used. Replace comb teeth on a music box the repair can not be seen and seems very strong. Its seems to be a perfect material for bezel repairs. I have used this stuff on electronic circuit boards with success, but there is always a problem holding the wick in intimate contact with the solder, heating until the wick has absorbed some solder, then removing wick plus solder.
Solder wick can also be used, it is basically a flux-impregnated copper braid that acts as a wick.
It is heated by the soldering iron, and the molten solder flows up the braid by capillary action. I have had the best luck using the ones that have a good coating of rosin, and use the smallest size possible in relation to the work so you don't overheat the item you are desoldering. For larger surfaces, use a 100 watt American Beauty electric soldering iron, and use fine steel wool 000 or 0000, and wipe off the solder when molten. Radio Shack sells them in the USA, but LaRose also sells them as air-blowers for blowing the dust off things. Not infrequently, the blob of solder you have just sucked off the substrate hardens in the tube of the solder-sucker.
