What glue or solvent to use to repair a resin model windshield?

Most of the glues you listed will fog or haze a clear plastic windshield.  The best bet is to use some type of PVA glue (Elmer's School Glue is good).  This will not affect the window in any way and hold it firmly enough for a deisplay piece.

This will do too.  It is basically PVA glue.

Sorry to hear your having problems.

For the last 20 years I have been using a 2 part CRYSTAL CLEAR 5 MINUTE EPOXY by Permatex. It won't "Haze" or attack your windshield as there is no solvents.

It can be purchased at most auto parts stores,"box stores", or on-line. Maybe even craft stores.

It isn't thin like water. It is fairly thick and is easy to apply in very small amounts in very small, specific area's. Most of the time I use a round toothpick.

Mix it fairly quickly.

I would have your items taped in place so the epoxy can be applied and your part won't shift if that's possible.

The less you apply, the less it will spread out if your doing small parts, and don't want it seen.

If you have some sample pieces you could practice on, I would try that first to get an idea of how to use the EPOXY and get the results you want before actually working on the piece your trying to repair.

Good luck.
