[TowerTalk] Loosening Rusted Hardware

Sun Apr 12 12:02:18 EDT 2015

Patrick,

I am NOT affiliated with Triflow Lubricants and do not receive any manner of 
compensation for mentioning their product on this reflector. Neither am I 
emotionally attached to the use of TriFlow. I will admit that I have used 
the product perhaps a dozen times... maybe ten times professionally and 
couple times at home when other penetrating oil products failed to do the 
job.

I had no intention of causing anyone to think that I was suggesting Triflow 
could compete with their favorite mix..... I WAS suggesting that it might be 
an alternative to a NIH syndrome product or mix as I had seen Triflow work 
when other solutions (pun intended) did not.

I also have experience with Permethrin and a number of other chemicals used 
by the US ARMY (27 year veteran - retiree). The real issue of "roll your 
own" chemical mixes is cost versus convenience, safety, and effectiveness. I 
doubt you have any liability, when you mix up Permethrin solutions for use 
on your clothes or animals but if used by others there is a potential 
liability as you know.

73 & DX,

Gary - AB9M

Gary, I read the student project materials with some interest.  This is
NOT what I read previously but it is unlikely that the two instances of
experimentation are coincidental.  It is possible (probable?) that the
student project at the link you supplied was stimulated by the reported
results I read.  The info I read had no 3rd world economics or "Green"
slant to it.

I find it interesting that so many folks post comments re their
"favorite" product when all these favorite products were demonstrated to
be more costly and less effective than the acetone/ATF mix.  Smacks of
the NIH (Not Invented Here) syndrome.  I tend to be an empiricist and go
with what works and don't pay extra for a name or highly advertised
miracle in a spray can.

I'm reminded of the situation with Permethrin (insecticide) the stuff
cloth is treated with before it is made into BDUs (military fatigue
uniforms - Battle Dress Uniforms).  You can buy Permethrin at Walmart in
small aerosol spray cans with a concentration of 1/2 of one percent, the
standard working strength.  You spray your cotton clothes not yourself
and it lasts up to 50 hot detergent washings.  Insects will not bite you
through treated material nor will they crawl more than a few inches
across the cloth before getting confused and likely falling off. I buy
Permethrin in 10% concentration (20X application strength) for $50 a
gallon which makes 20 gallons.  I did the math once and it took $1800
worth of the little spray cans from Walmart to equal the $50 gallon from
the farm and ranch store.

Most folks after being told about Permethrin prefer to buy at Walmart
and get little professional spray cans with instructions on the back of
the can instead of on the internet.  A gallon lasts me for years even
though it is also used to spray or pour onto the backs of our cattle to
keep flies etc off them.
