their technical department yesterday and they assured me that this epoxy =

Tim,

Is this ethanol proof?

Dave, Kurt



    In the voicemail message I received from the technical department at 

crosslink technologies (the makers of this product) the representative uses 

the term "proven resistance to a gasoline ethanol blend".  As you can see 

from the website Dave included it is designed for sloshing.

Do you think this would be acceptable on tanks already in covered wings and

flying?

    I think it could be done on a wing removed from the plane.  It took over 

an hour for the mixture to start to set up.  In this time I rolled my tank 

every which way to ensure that the entire interior surface was covered. 

You'd have to do the same with the tank in the wing. Removing the finger 

strainer would be difficult with the tanks still in the wing as the 90 

degree fitting will contact the bottom capstrip of the No. 1 rib when you 

try to remove it.  The other fittings should come out with out problem.

Here's an interesting article from 2001. I wonder what became of this 

intitiative.

Home page has a lot of links there to look thru. 

Didn't see any additional aviation news right off

though.

In sloshing your tanks with the Caswell epoxy systems ---- how did you

handle the Kreem that is already sloshed in the tanks by Skystar???

    I used 3 one litre cans of acetone one after the other with lots of 

sloshing.  The acetone / Kreem reaction produces gases so vent the tank 

regularly or it will blow the plugs out of the fitting holes.  By the time I 

used the third can it was more or less of a rinse.  The tank including the 

baffles appeared devoid of the Kreem.  I dried out the tank with the exhaust 

from my vacuum cleaner, waited a day and poured in the sealant.  The only 

problem I had was that the small sump below where the finger strainer sits 

was built up a little bit and the finger strainer would not fit back in.  I 

used my dremel to sand down a spot for the strainer. I think this can be 

avoided next time by raising that corner of the tank during the hardening 

process.
