[rebel-builders] Primed Fuel Tanks

[Al Paxhia]

Hi Bill,
I would be concerned about the primer for a couple of reasons. If the primer
is under the proseal it can break loose and your tanks will leak. I have had
a problem where I applied the primer too heavy (not in the tank) and it
pealed in sheets, that can clog your fuel screen. I would strip and clean
all the inside surfaces of the tank and reseal using only proseal. I would
not trust primer in a fuel environment.

This is my first time attempting to post a message on this site, so
forgive
my ignorance if I have done so improperly.

I am building a Moose, and am ready to close up my first wing. However, I
am now concerned that I may have been a bit over zealous in my zinc
chromating. I have chromated all the surfaces inside the wing, not simply
mating surfaces. This includes the inside of the tank skins, the ribs
within the tank, etc. Is this a problem? My concern is whether the zinc
chromate will withstand the prolonged contact with the fuel (I have not
chosen my powerplant yet, so I don't know if I will be running avgas or
auto
fuel yet). Any thoughts on what may be a really stupid question are
appreciated.

Hello Bill,

I Think it is very important that you remove the primer. No other solution. I do
sale indutrial paint in my business, I do have 2 big catalog of different paint and
primer, and I will not trust anyone for a long period immerge in gasoline.

Hi Bill
I can't answer you other than to say that if it were mine I'd remove the
primer from inside the tank.
It is especially important though that you don't have primer under the
proseal - ie that you built the tank before priming...

I had zinc chomate in my old plane fuel tanks that was exposed to
mogas and 100LL with no problems.I just finished my moose tanks with no
chromate inside.If the area was prepared there should be no problems.If you
want to remove the paint I use gun wash (Lacquer thinners) though the access
holes in the bottom wings.
