I purchased my SRT used. Somewhere a previous owner must have put some type of (?) plastic coating on the headlights. Each have what looks to be a "crusty/rough wave across the lenses side to side and partially in a couple of corners on each headlight. I can rub my thumbnail across it and it feels rough like you "could" scratch it off, but you can't! Tried using a headlight lense cleaner, nope-- didn't do anything. Tried using soft steel wool at one small corner and nothing. Anyone have any idea what I could try on a small area to see if it comes off? Otherwise I assume I'll need to replace them. Function okay... just ugly. Thanks for the help.
