Think I paid around $60.00 for a 4 oz jar of Coolamp several years ago. 
It's very expensive. But yes, it seems to last forever since very 
little is needed. Besides discolorations and unpredictable behavior in 
the case of Tinnit, another problem with this method of tinning is that 
you have no control over the thickness of the layer beyond the limit. 
There is no way you can beef up high current tracks for example. 
Neither can you hide pits and small holes.

Also, the solder paste method makes hand soldering SMD devices much 
easier. Just reflowing the solder on one pad usually fixes the device 
freeing up one hand to hold the solder and finish properly.
