First message to this list in years -
Sevaral months back someone mentioned a way to check formic acid strength 
while it's still in the container. Was it using the eye droper type device 
with the four balls in it used for checking coolant strength in a 
radiator? A hydrometer, I think its called.

I'm a little confused, what's the consensus on the most effective 
concentration when applying formic - 50% or 65%. My understanding is that 
in the 65-80 degree range 50% was the way to go.

Thanks for any info,
