| 341.1 | NO-NO-NO!! DON'T USE A POWER-TOOL.... | MAUDIB::CASEYA | THE DESERT RAT RC-AV8R | Mon Oct 26 1987 12:12 | 18 | 
|  |     Kay,
    
    DO NOT use a drill, Dremel tool or any other motorized method of
    trying to polish yer' canopy...the heat generated is more than enough
    to permanently disfigure or even melt the plastic!!  The only way
    to polish a canopy is by hand with a FINE rubbing compound...you might
    start with toothpaste; depending on the severity of the fogging,
    this might well be all you'll need to restore the clarity.  Be patient,
    it may take some time.  If toothpaste doesn't work for you, there's
    a very fine, reddish colored rubbing compound used by draftsmen
    and model-makers to polish plexiglas that works great on canopies
    and leaves absolutely NO scratches.  Call around to the local drafting
    supply houses to locate a source for this.  Good luck and let us
    know how you make out.  BTW, that's one of the "real" benefits of
    using Willhold RC-56 glue for attaching canopies/windscreens; it
    sticks like crazy, remains flexible and will not fog the plastic.
    
    Adios,	Al

| 341.6 | Tape and RC56 | LEDS::WATT |  | Tue Oct 27 1987 09:35 | 18 | 
|  |     When glueing canopes, I avoid CYA glues totally because they can
    run and ruin the inside of the canope.  They do attack the plastic
    as well before setting.  Any attempt to use kicker will really
    add to the mess.  I have been having good luck using tape to hold
    the canope in place while using RC56 adhesive.  This takes time
    and several applications.  I tape the thing on both sides and glue
    the front and rear first.  When this has set, I remove part or all
    of the tape depending on whether it will stay flat against the
    fuse.  I then add RC56 on the sides.  After making a mess of the
    first ship with CYA, I have done two with RC56 with excellent
    results.  By the way, Tower does have RC56 in their new big
    catalog, but I am not sure whether it is in stock or not.  It
    seems to me that I saw some comments in notes about availability
    problems with the stuff.
    
    Happy Glueing,
    			Charlie

| 341.7 | plastic polishing stuff from Aircraft Spruce & Specialty | TONTO::SCHRADER |  | Tue Oct 27 1987 18:12 | 16 | 
|  | I don't know if it will work on the type of plastic that model
canopys are made of but Aircraft Spruce & Specialty (a supplier of
materials for homebuilt aircraft) sells something called
"poly-sand scratch remover". This is a series of cloth abrasives that
will restore the finish of plastics. I guess that the way it works is
that you progress to gradually finer grits and eventually polish the
surface. Their catalog has all sorts of nifty stuff. Tools, hardware,
fiberglass cloth, resin, etc, etc, etc. (all aircraft grade, of course).
In case anybody is interested ...
