Attaching windshields

One of my biggest pet hates is attaching windscreens into my cars they never seem to sit in properly sometimes ending up with small gaps in the a pillar,Fujimi usually have locator pins when the windscreen parts mates into the body which makes it easy to line up, while Tamiya doesn't it can be annoying when trying to glue it in place, i usually use 2 part epoxy to glue my windscreens in place, what do you guys use? I also use tape to keep it in place while the glue dries, do you guys clamp down your wind screens while the wind screen dries? or use tape.

I glue it with Kristal Clear and hold it in place with tape if needed
