How long have you guys stuck them in the oven for, and at what heat?
If just to get the water out, i use a blowdryer pointing to the back at about 10 inches distance for half an hour.
Nah, unfortunately my reflector has fallen off the rear lens and is sliding about inside. It's actually a job I've been putting off doing; I decided I'd rather change the radiator than try to open the rear lights!
