1659.0. "help-fuelproofing seams" by NCMAIL::BLUMJ () Fri Mar 24 1995 09:00

    I am close to covering my second powerplane.  I noticed on my first
    plane that fuel has creeped under the covering, particularly on the
    stab.  
    
    I took particular care to iron down the seams- but to no avail.
    
    One member of my club uses K&B clear epoxy paint and brushes it onto
    the seams with a small brush.  He claims that this totally solved the
    problem.  This two part paint costs $15, however.
    
    Any other/cheaper suggestions that work?
    
    
    Thanks,

1659.1Sorry, couldn't resist! :)WMOIS::WEIERKeep those wings spinning!Fri Mar 24 1995 09:048
    
       Jim,
    
          You should think about trying electrics, that way you wouldn't 
    have to worry about the "fuel creep" ! :)

    Some folks recommend putting a bead of CA on seams to seal them..
    
    Rather than K&B clear, you could probably also use just regular epoxy
    thinned with alcohol.  (as long as your base color isn't white! :-)
    
    I found that trying to seal the seam usually ended up more of a mess
    than the original problem....  Maybe you aren't using enough heat?
    (Or did you forget to take the backing off?? :-)
    
    cheers,
    jeff

    RE: -2
    
    Dan, even I do not recommend electric power for a tow plane!
    
    Re: -1
    
    Jeff, I am under the assumption that fuel creep is quite common.  I
    used Ultracoat with plenty of heat.  Covering was definitely peeled
    off.
    
    Thought about the epoxy thinned with alcohol method, but I am a little
    gun shy of ruining a perfectly good covering job with gooey epoxy that
    won't cure.  I have had bad luck thinning epoxy with alcohol in the
    past.  I am infamous for trying to save a few bucks and ruining the
    piece in the process.  What do they call it - Penny wise and pound
    foolish.

Jim, 

  There is such a thing as too much heat as well. You can bake away the adhesive
with too much heat. Ultracoat is pretty low temperature. I never use "monocoat"
temps on Ultracoat. Wayne Field mentioned a guy he knew that used to rub down
his layers with alcohol/acetone before putting on the overlapping layer. Maybe
he can relate that guy's technique first hand?

1659.5Black Baron Something-or otherCOWPOK::TAVARESFri Mar 24 1995 10:086
    Hi gang.  I'm back as a contractor, for a while.
    
    I've had good results with a clear coat made by Black Baron.  I forget
    the name, I've used it over decals and stick-on art (I use a lot of
    stickers from the car guys on my planes), and the stuff has kept them
    from peeling off.  
1659.6RANGER::REITHFri Mar 24 1995 10:221
Welcome back!

    re: -1
    
    Thanks for this info.  I looked in the Tower catalog and the stuff you
    describe is Coverite Brush-on epoxy paint.  It is available in clear
    for $5.69 which is better than $15 for the 2-part K&B product.  I think
    I'll give it a try.
    
1659.8What if...NCMAIL::BLUMJFri Mar 24 1995 10:3110
    It does seem that with management being *THE* stated core competency of
    Digital(stop laughing guys!), that in the end all the people who do the
    work will be contractors.
    
    Wouldn't it be something if all the ex-noters were hired back as
    contractors and the RC notes file were restored to it's former
    vitality.  Imagine if Casey,Tombaugh, Antry, Henderson, Watt, Ajai, all
    the Brits, etc. were back!
    
    Well enough daydreaming....

    Jim,
    
    I assume that you have been following Dan's notes in "Let Us Spray"..
    
    You should have the same concerns as Dan does..  The Black Baron takes
    longer to cure.  
    
    If you were nearby, I would let you use some of the K&B clear that
    I have..  I always have a couple of cans around..  It is good stuff!
    
    cheers,
    jeff
    
1659.10Not An EpoxyCOWPOK::TAVARESFri Mar 24 1995 14:579
    No, its not epoxy--its a 1-part stuff.  I'll write it down and post on
    Monday.  
    
    I picture the eventual evolution of DEC to be 4 guys in a garage, their
    desks arranged facing one another, passing pieces of paper between
    themselves and talking on the phone.  
    
    Though the reasons why I was axed have more to do with incompentent
    managers finding a way to keep their jobs than anything else...
1659.11RANGER::REITHFri Mar 24 1995 15:134
Nah, the papers will never be exchanged. "proprietary info" and "need to know"
8^)

Different view from out here, huh?
1659.12Glas KoteCOWPOK::TAVARESMon Mar 27 1995 11:333
    Its called Black Baron Glas Kote, #4500.  It sprays on easily from the 
    can and it dries in 15 or so minutes.  Great stuff over decals.  Bummer
    is that its relatively expensive: $6 for a small can.
