Peter:

Have you sent your tank in yet?  I being one who having to "hack my tank out" 
have
a tank that I bought a couple of years ago from Bob Berube.  I don't know
how long he had it so its processing is questionable.  I had been planning on
fabricating a metal tank for installation when I got around to it so the new 
plastic
tank has been sitting around to be used as a model.  However I may change
my mind and put the stock item in it would be good to have the proper processing
on it.  If the lot charge could be spread over 2 or more tanks it would
be beneficial.  Please  get with me if this is something to be considered.

Thank you ,

Hi Fred,

Indeed it is an industrial process on the loose piece-parts in 
temperature/pressure
controlled chambers filled with controlled volumes of Fluorine. Different
parameter combinations for different levels of fluorination (they have 9 
different
levels).  They typically are set up to do large mfg runs of auto gas tanks,
plastic gerry cans, shampoo bottles etc.etc.  so I'm eating a minimum charge
(which they somewhat reduced for me) which is distasteful but understandable,
and worth my piece of mind (hopefully preventing me from potentially hacking
out my tank 5-10 years down the road.).   If I had 4 tanks or so, I could have
done it much more cost effectively.

They have 4 facilities which can do the Auto-tank level, and I chose their 
Atlanta
plant for it's relative proximity.

I'll keep folks posted how it goes and can provide contact info for any 
interested.

Cheers,
Pete

Peter,


Since your tank is yet to be installed, I expect that you will be taking it 
somewhere
for treatment. As one w/ an installed but yet to be filled w/ fuel tank
of similar vintage, I'm wondering about the treatment you anticipate and how
it is done...(?)...Is it something which conceivable could be accomplished on
an installed tank if the fuselage were trailered to a facility which does this
sort of thing?


I wouldn't expect the treatment would be offered at the neighborhood "gaairage"
(phonetic sp.? lol), but I've no idea what type of facility does this sort of
work...do you live near a factory which supplies the auto industry?


Please keep us posted on this,


Fred

thanks all for the info/links.  Looks like mine *should* have been done, but 
since
I still don't know to what level, I decided to go get it done again, this
time to automotive level standards.

Based upon the softness of the tank material, I presume it is LDPE.

Cheers & thx,
Pete

Introduction of fluorination was in April 1997:

I have assumed that my tank from the year 2000 was treated and did not repeat 
it.
In any case any spilt epoxy bonds to it extremely well (as well as to itself)
- which is supposed to be a side effect of fluorination.

my kit is from 2000 as well, and i asked the factory (before the merger) back in
2008 if my tank fell into the post non fluorinated time frame, and they
responded this after i indicated the desire to purchase a new fluorinated tank.
so based on what i was told i would believe yours should be ok. If its not
much cost involved the second treatment would probably be a good investment.

   Would anyone know which it is?  (I think I had heard LDPE)

   I am asking because I am about to spend some money getting my
   still uninstalled tank Fluorinated or Re-Fluorinated - since I
   cannot be sure to what level it was done by the Europa factory (if
   it was done at all back in 2000) and I wish to avoid the swelling
   and cracking problems some are seeing in service.

   I am choosing to Fluorinate to the same level (AL) as the auto
   industry (by Fluoro-Seal International LP)

   Thanks in advance,
