    Dear All:

    I am having a ding repaired. Anyone know the name of a good outer =
    surface color match using polyurethane paint?

    My a/c has a gel coat. Unlike later a/c, my a/c is not painted in 
    polyurethane.

    Can you paint over gel coat with polyurethane?

    What about get paint custom-mixed?

    (see you in September, Ted)

    Hello Bruce and all,
     
    To answer your question about urethane over gel coat, yes. Here at the 
    'Possum Werks we shoot urethane over gel coat all the time, but it depends  on the
    application. Gel coat, even the high quality German stuff, yellows faster  and
    to a greater degree than urethane. So, the potential for a small repair to 
    show up a few years down the road as a noticeable color blemish is there. Gel 
    coat is also considerably more brittle over time than urethane and that is why
     it cracks and crazes. You can slow the progression of the yellowing with WX 
    Block or a good hard wax, You can also slow yellowing and crazing with 
    periodic sanding and buffing, but you have to know how to sand and know the  right
    buffer to use and how to use it or you can ruin your finish.  What we  use
    just depends on the application at hand.
     
    Urethane stays much more flexible than gel coat and thus isn't subject to 
    the crazing and cracking that gel coat almost always winds up with. We generally
     use urethane over gel coat when we are doing a complete refinish and the 
    customer doesn't want to take all the gel coat off (IOW, down to or nearly down 
    to the underlying cloth).
     
    For incidence, we are currently doing a refinish on an ASW-27. The 
    Schiecher's all have gel coat finishes. This -27 is a mid '80's vintage and  has
    considerable crazing and yellowing. We chose to use urethane over gel  coat in this
    incidence because we are trying to cover and fill the crazing that  we weren't
    able to sand out. Most single stage urethanes cross link  the paint molecules
    with isocyanate. This provides excellent UV  protection for the underlying
    glass and resin from UV. The cracks and  crazing expose the underlying cloth and
    resin to UV, so it's very important that  it be protected or else stuctural
    issues will eventually develop. With this  method the customer will have many
    more years use out of his bird without having  to worry whether or not the
    underlying cloth and resin are being destroyed by  UV. Not a perfect fix, but it
    will give the owner several years of a  beautiful, almost factory quality
    finish once we're done.  Unfortunately, the crazing will eventually return,
    probably in 7-10  years, but the underlying cloth and resin will be protected until 
    then.
     
    We also have an LS-4 in the shop for an aileron bellcrank inspection, 
    replacement, and lubrication. This required that a 4" hole be cut in the  wing to
    get at the bearings we needed to lubricate and or replace. This airplane  also
    has a gel coat finish and considerable yellowing has occurred. We  chose to use
    gel coat in this incidence because urethane would show the patch  later on
    because the urethane stays white and even with a perfect match and a  good
    blend, the gel coat will continue to yellow and eventually show the patch.
     
    Pigment is how we color match. You can get pigment at any good automotive 
    paint store. Using pigment to color match is far more art than  science, but gel
    coat is usually very thick compared to paint  and it can also be lightly
    sanded some to remove  surface yellowing and help blend in a patch. The very top, 
    outermost surface of the gel coat is what yellows and it's a good idea  for
    the longevity of the finish to sand the gel coat entirely every 5-7 years to 
    remove micro cracks and crazing before they become visible to the  eye.
    Eventually, you will get down to the cloth with periodic  sanding and buffing, but by
    that time most of your prep work is done for a  refinish. At that point it's
    easy to scuff and shoot urethane over the  remaining finish. This is the right
    thing to do, but few ever do it except  the hard core racing crowd because
    it's very labor intensive and  thus quite expensive. Please note, I'm not trying
    to say that everyone  should pick up a sanding block and go after those
    yellowing wings. You must know  the proper technique to sand curved surfaces, the
    proper blocks  to use, and what grit to use or else you run the risk of
    changing the  profile of the surface you are sanding! If you aren't absolutely sure
    how  to do it, please leave it alone!
     
    We can usually blend in a patch by lightly sanding around the area to be 
    patched to remove or fade yellowing. This is done with 600 or 800 grit wet. This 
    removes the yellowing to some degree and helps blend in the patch. Further 
    blending is done with the buffer and polishing rouge. Again, this is more  art
    than science and it's something that you develop an eye for over time. Once 
    it's been shot with gel coat, color sanded and buffed, usually you can't  see
    one of our patches in sunlight. Most patches will show in fluorescent  light,
    though, regardless of how good you match it. Fluorescent light will show  all
    flaws where sunlight tends to hide most flaws.
     
    The key to a patching paint or gel coat is preparation, preparation,  and
    preparation. A common misconception is that paint (or gel  coat) "hides" flaws.
    It doesn't. Paint and gel coat both enhance  surface flaws. The surface must be
    absolutely smooth before you paint it  or the flaw will jump out at you like
    a screaming  monkey. Applying urethane or gel coat to raw fiberglass is also a
     no-no because it's a recipe for pin holes. Ditto if you fail to remove all 
    the wax and grease from the surface you are painting before you  shoot.
    Working with "hardened" paints and gel coat finishes isn't  difficult, but it does
    take patience and a knowledge of how to manipulate the  product. You'll need a
    good respirator and a well ventilated shop, too.  Temperature is also key.
    Urethanes and gel coats alike both like to be shot  warm, but not hot. We like to
    shoot in the 75F-90F range, then apply heat  afterwards. Lower temps and you
    will sag and run. Sags and runs  aren't a huge problem with gel coat or
    urethane because they can easily be  sanded out, but you try to avoid them because
    it's just more work. Shooting  at higher temps make the product kick too
    quickly and the paint/gel  coat won't flow out smooth, regardless of how much
    reducer you use. You  wind up with "orange peel".  This too can be dealt with too,
    but it just  means more sanding. It takes some patience, practice and a good
    gun to  get it right.
     
    If you'd ever like to see how it's done, feel free to stop by my shop at 
    TN89. We generally have anywhere from 1-5 sailplanes in the shop or waiting in 
    trailers outside at any given time, but occasionally we run out of  work, so
    it's best to check ahead. If you come at the right time I can  teach you more
    about paint and finish in one afternoon than you'd ever care to  know. For most
    people, once they see what is involved, they prefer to just  leave it with us.
    Sanding is the fastest growing spectator sport in the northern  hemisphere!

    Simtec Coatings
    16666  Smoketree St.
    Hesperia, CA 92345          
    760-244-2774

    Hey Roland,
     
    Yes, Simtec is where we get our gel coat. It's good stuff as far as  gel coat
    goes. Be careful though, gel coat uses MEKP as a kicker. This is  hazardous
    stuff! Use a good respirator, ventilate your shop and cover all  exposed skin
    if you intend to spray this stuff.
     
    For urethane, we prefer De Beers "Berocryl 400". At $260/gallon, plus 
    hardener and reducer, it's not cheap, but it is head and shoulders better  than PPG
    or that Sherwin-Williams crap. FWIW, we used to use Sikkens urethanes. 
    Sikkens is the same paint Mercedes and Porche use, but Sikkens,  with the current
    exchange rate to the Euro, and a recent price  increase, just priced themselves
    out of our reach at roughly $900/gallon  our cost, plus thinners and reducers.
    Sikkens is the best, though, but De  Beers is a close second. It's engineered
    by the same folks as who  engineered Sikkens urethanes,  it just costs less
    and unlike  Sikkens, it uses the same kicker for the paint and the primer and
    the same  reducer for the paint and primer. This saves you some money in the
    long  run. IMHO. having shot all four varieties, I'd avoid PPG and 
    Sherwin-Williams urethanes. They don't shine as well as De Beers and they don't  cover
    near as well. If cost is no object, use Sikkens urethane. Otherwise,  I'd use De
    Beers Berocryl 400.

    Dear Roland and John:

    Thanks for the info on finishes. Good stuff. One question: Roland is their
    2481 an off white finish or is it brilliant white? The Web site you
    mentioned says their 2400 series is a "super high gloss topcoat". Sounds
    good.

    Best
    Ted

    The  procedure does not require painting skills. Sanding is essential to get
    a  straight, smooth surface. If it is not perfect the first time, just do it 
    over. You'll get practice.
     
    Hello Roland and all,
     
    Well, I've never seen it done that way, but I suppose it would work. The 
    only thing I would add would be to sand at alternating 90 degree angles, 45 
    degree to the curve if there is one, up through 800 grit. Then, we switch  to 1500
    sanding 45 degrees to the previous sanding. This will remove any  scratches
    left by the 600 and 800. If you really want a mirror, go to 2000, but  you
    might find you make your patch shinier than the rest of the area and that  will
    make it stand out. For an invisible repair it's important to not only  match
    color, but match the shine, too. We usually stop at  1500 because 800 will buff
    out to a very shiny surface, but sometimes  you can see 800 scratches in the
    right light. The 1500 at a 45 degree  angle to the other sanding will remove any
    residual scratches left from  previous grits used.
     
    Another ingredient I would add is the Klingspor paper we use. We've  tried
    them all and this sandpaper puts the rest to shame, even  the pricey 3M stuff.
    It's made in Germany and is available from  the importer over in Hickory, NC.
    It cuts faster and lasts longer than  anything else we've tried. It comes in
    25' rolls and is sticky backed, so it  sticks to the sanding block, even when
    wet. It's great stuff and I highly  recommend it. It's actually reasonably
    priced, too. _www.klingspor.com_ (http://www.klingspor.com)  Once you've tried 
    this paper, you won't use anything else.
     
    Anyway, hope it helps!

    Regards,
