IMO these things are a total ripoff, soldering irons are cheap. Like paralyzed said, there are just too many kinds, and they are hard to identify, even for a seasoned hobbyist.

I've repaired motorcycle bodywork, very successfully using only a regular 15/30W iron and some excess material from the work itself- this is the only way to assure you have the right base material. The trick is swirling the material back and forth between the two pieces being repaired, letting it solidify then applying some more. For the filler material, just cut slivers off the piece where it won't be needed and pin one end of the sliver down onto the joint, then work it in, making sure you have good cohesion.

Just keep your face out of the fumes!

Ask yourself what you are really getting with the kit, a glorified soldering iron and some almost worthless filler rod- do it cheap!

Need more info let me know.....
