A bit of an experiment! (Used Bondic to mount a windshield)

[Art Anderson]

In deciding just what would be the best way to mount the windshield glass in my '61 Ventura, I decided to try Bondic, but a big question:  Would the UV light cure the Bondic THROUGH the clear plastic windshield "glass".  I know that ordinary glass does filter out a lot of UV light, but would the clear plastic?  The answer is, NO.  I was able to cure the Bondic adhesive THROUGH the clear plastic.

Good information that I'm sure will come in handy for many. Thanks for sharing!

A suggestion: Maybe you could get "Bondic" in the thread title somewhere so the tip is easy to find and doesn't get lost over time.

This is a pretty important point about Bondic. One reason it's doesn't work as a glue bonding two pieces in a butt joint, unless at least one piece is clear. Any Bondic that squeezes out of the joint will cure though ... surrounding the joint with a weld.

Yup--I'e done a few test "welds" with the stuff, and found that it likes to have a bit of excess squeezed out around the joint so that UV light reaches that, but once it does, in a few seconds, the setting process reaches inward.  After that, a bit of sanding, and all is good!

Art, what do you think about using this for gluing together the clear parts of the old MPC/AMT Show Case trailer? There are some fairly long seams between the roof and the sides.

Give it a shot!  The stuff is water-clear!

I've tried Bondic to try gluing a read window for a Subaru Legacy together with Bondic. The window was broken in 2 through the middle. Bondic will not make the seam invisible, though it could be the looking fix for this "impossible" task. I was careful to wipe all Bondic squeezed out from the joint and it cured through the clear plastic, but it is pretty visible. Sorry, I don't have a photo of the repair .. this broke all the way across before I tried to fix it.

What about casting a replacement for that piece out of Bondic?

I don't think that would work. I would need to be a two piece mold and would be near impossible to fill as Bondic is thick and doesn't flow. The light wouldn't be able to reach the material through the opaque molds, unless you had clear, 2-piece molds. Keeping the transparency would be a little work too and would be needed to be sprayed with some acrylic clear before touching it.

I addressed some of these problems in my Bondic thread.

I actually took a whack at repairing a windshield with it for fun; the Bondic really wouldn't flow into the crack so I drilled a 1/8" hole through it, covered it with a piece of a clear plastic bag on one side, and filled it with Bondic from the other side. Sadly it wasn't an invisible repair even after polishing it; oh well...
