How to glue smooth vinyl to lexan, or to small steel washers, for a
short time?


I'm still working on putting in a polycarbonate (lexan) replacement for
the broken glass rear window in my convertible.

Because I'm working alone, I thought it would be good if I could "glue"
the polycarbonate or its vinyl backing sheet to the vinyl** strip (part
of the rear curtain) that the glass was bonded to originally.

**At least I think it's vinyl. It's black and shiny (where it used to
be fused to the glass) and flexible and 7/8" wide and maybe 3/16"
thick, and can be seen behind the edge, the outside 7/8" of many, most,
or all convertible rear windows. if you peek under the outside layer of
the top.

Then if they were glued together, when i drilled a hole, I would drill
through the carbonate and the vinyl at the same time, and the holes
would match.

The bond doesn't have to last more than 30 minutes if things go well.
And I can redo the bond if things go badly and take too long.

And it only has to be strong enough to hold the vinyl in place. The
way the top works, the vinyl is held up pretty much already. (Although
I may have to lower the top a bit to pull the upper fabric back from
over the border strip where the vinyl is.


Any suggestions about adhesive?


I was thinking of contact adhesive, At the url I posted in the
immediately preceding OP, someone says "[Contact bond adhesives] are
almost a "universal" general purpose cement, and will bond a variety of
substrates to one another such as wood, leather, metal, etc." Does that
include polycarbonate and vinyl????


I also wanted to use an adhesive to bond the vinyl to steel washers, so
they would stay in place while i'm outside the car. I'd put the pop
rivets in to several holes, go inside the car and push the washers up
the pop-rivet, where some kind of glue would hold them in place, until I
could go back outside and crimp the rivets. (I've done tests and know
how to use pop-rivets without breaking the lexan.)

Any suggestions here?

Here also I am thinking of contact cement. I bought a fresh bottle

The temperature tomorrow is supposed to be about 51 and Monday about 58,
but I can use a hair dryer if needed to speed contact cement or other
drying,

Thanks a lot.
