slightly related but how do you get the windscreen out, can you break down the black goo with kerosene then come back a day later and have one guy push the windscreen carefully from the inside while the other guy "catches it" (i can see this ending in disaster )
or do you just have to go slow and steady with a butterknife to break the seal (maybe dousing the knife in kerosene)
or do you just bite the bullet and have someone remove it for you (noooooooooooooooooooooooooooooooooooooooooooooooo oo!!!)
