Sloshing compound - was Proseal
Posted: Fri Feb 17, 2012 10:43 pm
I'm with Wayne - avoid sloshing if you can !!! I've seen
some <really> aweful messes that necessitated removing the top of
the tank, and days of work to clean up !!! It only takes a bit of
it to lift and plug your finger screens to spoil your whole afternoon !
The 'red stuff' was used by the factory a few times, many years
ago. I always thought it was Randolph ..... Don't think it stands
up too well to auto gas - you could ask Aurele, because I <know> his
Rebel had it. When I test flew it, gas was running out of the wing
when I taxied in !! They drained it, dumped in a couple of quarts
of the red stuff and rotated the wing several times, then drained
out the surplus for use on another wing !! It was dried overnight
with the "shop-vac trick", and we flew it out a day later,
all the way home to Longlac,ON mostly running 100 LL, which was
likely a good thing, as mogas might have dissolved it !! Since the
912 prefers auto fuel, I guess it got lots of it for the next few
years - didn't leak then, as far as I know, but I think Aurele had
some problems. Another Rebel adventure ! :-)

Alister(and All), you should be all right using av gas and note that there
are sloshing compounds that are compatible with alcohol, but the one I have
seen (white Randolph) is much thinner and doesn't seem to fill holes as well
as the old gooey Randolph yellow stuff (that alcohol eats), instead they
just pour right through. OF course I know this from using the stuff in
customers Zenair floats that are impossible to get inside to fix seepage
correctly, unlike a good set of Murphy's where you can do it right with
proseal or Sikaflex.
I have also seen Red sloshing compound in a few Rebels. Does anyone know
what Brand this is and if it is alcohol compatible??
I also have to fess up that I have the old style yellow (non alcohol
compatible) Randolph sealer in my tanks, but just brushed across the lower
tank skin rivet heads. My tanks have the RV1410 style normal rivets
throughout and not the tank style RR6402's, so being neive at the time of
construction in 1993 I wanted to be sure that at least the bottom skin held
fuel. On my first big cross country, to Oshkosh 1995 with my son, we got
100LL fuel in Escanaba Michigan (Delta airport). While sitting under the
wing at Oshkosh fuel drops starting hitting me on the head from a few of the
lower tank rivets. After our return to Canada I drained my tanks and
refilled them with Hammond's 100LL from Midland Airport (and what I now have
here at home) and all the leaks stopped and have never leaked again in
almost 8 years!! It appears that something in the fuel at Delta softened the
sloshing compound so that the fuel could leach past it and through the rivet
mandrels.
I talked with many people about this over the years and have heard very
similar stories of questionable fuel at various small airports throughout
the USA. They may cut it with anything to stretch it and help the profit
margin, so be careful and check your fuel for alcohol etc on a regular
basis. Easy to do, just put water in the test gauge first and if the "water"
mark rises after you put fuel into it (provided of course you know there
isn't any water in the fuel sample) you have fuel with alcohol in it.
Cheers,
Wayne

sloshing compound!!)
I have to say that I used sloshing compound on my tank and have
had no trouble to date (5 years now) but then I do not use auto fuel
