Ok i have a better solution to those yellowed lenses. cost of 5 bucks and no removal and has lasted me 3 weeks in rain so far. Go to Wal-Mart and in the auto detail/cleaning section look for some stuff called Meguiars Scratch-X its next to things like compounds. Just rub it on with a little force then polish it off. took me like 8 minutes for both lenses and the bit under the grill. looks like new, ill inform you guys if it does yellow again and when. I put on spray wax after so that may also hold out longer.
