Yea while they're off. If u wet ur finger, it wont stick to your fingers. I've never sealed headlights before but lots of windows, doors, and anything else to do with construction.
After your done, stick a 16 penny nail down in tube, wrap electric tape around it to keep air out. That'll keep it from drying out, just n case you need it later down the road.
