And put on LOTS !!! ...................
(no one is ever going to SEE it ........ and "more" will better your
chances of no leaks )
We went out an extra rib to get 230 Lts ..... used one 1 Ltr kit per
tank base & sides & ordered another just to do the 2 tank tops ... ( 3
ltrs of Pro Seal in total ) .... and we've NEVER leaked a single drop !

If you don't want the mess of peanut buttering the Pro-Seal when you
assemble you
might want to try the caulking tube method. You can buy empty tubes
for your
caulking gun for next to nothing, mix your sealer and put it in the
tube. From
there you just put it on like you would to seal up your bathtub. The
info is on
my site (
www.elite583.cjb.net) under wings, scroll down to "Wet Tank
Sealing" and
there is a pic of the tube and info on where to get them.
Sorry, no photos of it in action, cameras & tank sealing don't mix!
Cheers,

Hi Bill !
Welllllllll ....... there are some thoughts that the brushable
ProSeal
isn't quite as durable as the thick black stuff ...... but,
maybe ....
it's your airplane.....
One trick when doing large pieces - like tank skins - is to install
all
the rivets and pull at low pressure - maybe only 10 lb -- the idea
is NOT
to pull the rivets to pop, just squeeze the ProSeal out gently.
Once all
the rivets are in, go around and pull again at maybe 20 - 30 lb.
pressure,
wait a bit for squeeze out, then crank up to full pressure and pull
to
pop. This gives the PS time to spread out a bit, and reduces the
gap
between pieces - less chance of leaks, and a stronger, tighter joint
!
Many builders join & fillet with the thick stuff, then brush the
thinner
PS over everything, especially rivet stems & heads, just to be sure.
The
important thing there is to be sure to clean & prep the surface
before
brushing ! Wipe with acetone, then scotchbrite until shiny -
ProSeal
immediately. Do not wipe with shop rags - may contain oil - even
from
skin on hands !!
Hope this helps !

The brushable ProSeal would be easier to apply mating large

Hi Bill !
Thinning ProSeal is not a good idea - but I think he used the
"brushable" Pro-Seal - it's about like honey. Available from
Leavens.
The big caveat is - don't seal up the inlet completely - just
stuff
the vacuum hose into the tank - or you might collapse it !! The
idea is
just to reduce the pressure "a bit", to suck the ProSeal in.
Many builders have used this trick with good success - it can
also
help if you have a leaky rivet. Just put a drop or 2 of brushable
PS on
the rivet head & wait for it to be sucked in - add another couple
of
drops, then turn off the shop vac & wait. :-)

I had a tank leak in the wing I couldn't get to. This occurred
in a
quick build wing. The solution that was suggested to me and
work was to
apply a vacuum cleaner to the tank and apply slightly thinned
proseal to
the leak area. Let it such in for a minute or two depending on
the size
of leak
and
thickness of the proseal. This worked great for me.
A lot better than sloshing.
