Since it's such a common problem, do you think the original UV protectant
wasn't enough?


My limited eperience is that UV protection wears out after while. I've
used various outdoor finishes with UV protection and after two years it
is still good aside from the uv.

question...
does it make sense to apply the UV protection coating to newish lenses before they get really yellow? and to reapply it periodically so hopefully you won't have to polish them.


Also, from experience, do not press very hard on the front of older headlights, the plastic aiming parts inside are getting old and if you press hard enough they can break and then your lights will not be aimed correctly.
