I'm about to buy some more Tamiya kits, but they have windshields and headlights. Up until now everytime I've tried gluing those types of parts, they get taken over by fog. I used to use superglue, then switched to Tamiya extra thin, but that seems to fog them over too.

Any tips?

A coat of Future (now Pledge with Future) will prevent fogging. Dip the part in a container of Future and let it dry for 12 hours, then you can use Cyanoacrylate (super glue) as an adhesive. Any liquid cement (like Tamiya extra thin) will melt the clear part or frost it if not applied carefully and sparingly. You could also use a variety of water based adhesives for clear parts, like Testor's Clear part cement, H&S crystal set, or even Elmer's glue.

I use pva glue for clear parts. However, I do recommend dipping the part, in Future . It will look more like glass.

Use Revell Contacta, which is made for clear parts. Standard product, easy to use. Approx. €2 per bottle.

Try Testors clear part glue.
Works well.I apply a thin coat around window frame with the head of a toothpick.

a water-based white glue, acrylic glue or pva adhesive will be strong enough to hold the part, and will not attack the clear styrene. Also, avoid spraying clear flat coats over clear parts, as they will also fog the plastic.

I recommend this too
