gluing mirror to plastic (car door mirror)

    Got replacement mirror glass for our Fiesta car door mirror. It can be
    fixed with a sticky pad supplied or with glue. The sticky pad will not
    work with the glass carrier used by this door mirror, so it has to be
    glued. The plastic is the type of black brittle stuff that discolours
    when you bend it.
    So, I need to know the best glue to attach the following:
    1. A mirror to plastic (the mirror silvered surface will be in contact
    with the glue)
    2. Plastic to plastic (to reattach the mirror carrier to the holder
    which has broken clips)
    Thanks,
    Simon.

    Why not? because it is a "spider" with thin webs, so there isn't enough area
    presented?

    In my experience, glue repairs on car mirrors seldom work for long. You
    might stand a better chance if you can take off the forward facing "fairing"
    and apply epoxy from the back of the mirror to bond the glass to the holder
    / carrier. Or genuine Duck tape (which is stronger and more durable than the
    cheap clones).

    You may find perfectly adequate clone mirrors on eBay at about a third of
    the main dealer price. This is what I did after repeated failed repairs on
    an Astra.

    Unfortunately that's true of most thermoplastics. Brittle probably just
    implies it contains a lot of filler.

    Similar to that.
    The foam pad occupies the middle say 80 percent of the mirror, but
    the plastic it has to attach to is like a narrow frame around the edge
    of the mirror. This "frame"
    should clip over and around a central circular piece the is controlled
    by the motor. The problem
    is the clips are broken, so it needs to be glued. Also, the area the
    mirror is to be stuck to is not
    flat, but has various raised areas and nibs etc. These act to hold it
    around 1mm from the rest of
    the plastic. The foam would therefore have little contact area, which
    leads me to think it should
    be glued.

    Here, do you mean an entire door mirror unit, or just a mirror pre-
    bonded to
    the carrier ?

    Thanks,

    Having gone through a similar pattern, I agree with Newshound - buy a
    complete new unit. One little linkage in my electric mirror was
    damaged along with the glass breakage - after trying several
    approaches to repair (and having not listened to good advice "replace
    the whole unit") - I eventually replaced the whole thing.

    Door mirrors getting damaged is a common occurence, and there's a well
    established market of pattern parts if an original part from your
    local dealer is too expensive.

    When you say "unit", do you mean the entire internal parts inside the
    mirror "shell", or do you mean an entire mirror (including the colour
    coded shell) ?

    IME impact adhesive sticks anything to anything, stays flexible, and is
    waterproof. Uhu, Pound Shop?
    I've repaired more mirrors that way than I care to remember. For years I
    drove a van with sticky out wing mirrors in Inner London, so it was a
    frequent occurrence.

    I guess this should stick the plastic - looks like its made for it :-

    Yes, I mean everything that hangs off the door. Generally spares are
    available as mirror glass, or the complete thing. Obviously mirror
    glass is quite a bit cheaper, but unless it's a straight in fit, I
    wouldn't bother.

    Colour coding on mirrors is a PITA. My VW van would have had them
    originally, had a pair in black when I bought it - and I've since had
    to replace one - the whole unit replacement consists of 2 electrical
    connections and 4 screws.

    They're hardly mega-money on ebay:

    "Mirror Mate", which comes from Screwfix for not very much and looks
    like your typical DIY gooping mastic - except that it doesn't damage
    the silvering on mirror backs.

    If you want to see why this is important and you're near Chepstow,
    then go into the furniture warehouse place near the river and look at
    their posh and expensive "Venetian" mirrors, made of multiple bevelled
    panes. Then stand back and look closely at the emerging figure-8
    trails clearly etching their way through the back of each and every
    pane. Someone made an expensive cock-up there!
