I'm ready to mount the perspex headlight covers but it strikes me there could be a problem with condensation and thus transparency during rainy periods. The headlights (Moke) have a rubber seal which should prevent any moisture coming into the enclosed area from splash under the front guard but I wonder should I attempt to seal the perspex covers to the bodywork as well? If moisture does get in it will be a PITA to remove the covers and let it dry out.
I wondered if I should drill a drain hole through the fibreglass under the headlight rim and allow small gaps to remain where the perspex cover doesn't fit snugly to the bodywork, creating some kind of airflow/ventilation, or will that just encourage condensation under the covers?
Does anyone have experience with these types of covers or any comments? Thanks
