I have experimented with several types of glue for various applications when building plastic models and discovered a unique way to avoid glue stains, smears, and fogging.  I was using acrylic FUTURE FLOOR WAX to dip my windshields and headlights in to give them a clear sheen and glass-like finish when it dawned on me that Future adheres to Future better than glue bonds plastic together. Now, I not only use it to dip windshields and headlights, I use it to attach them to my models.  Attaching headlight lenses to chrome bezels with FUTURE keeps the chrome and the clear lens absolutely unmarred.  And, it holds better than glue.  Attaching windshields and side windows can also be done this way.  There is another bonus to using Future as glue........when soaked in water over a period of time, it becomes cloudy and loosens it's grip so you can disassemble your model without breaking the parts!  FUTURE can also be used to attach canopies and after drying, it can be painted over.  The bottom line is that it does not show when dry, and it does not mar paint or chrome!   I also use FUTURE FLOOR WAX for clear coats in my airbrush but, that's another story.  I hope this tip helps you with your modeling.

This VW BAJA BUG does have a windshield but, as you can see, it is so clear that it is almost invisable!
