Pitted Windows

[n33k0]

One of the many things that need attention on my truck is the door glass. It is pitted, not excessively, but it's annoying and very noticeable when the sun hits it just right. Is there any way to repair the glass or fill the little chips and pits? Is it worth the cost and time to do so? I know new glass is (relatively) cheap, but if I can get the old glass to look decent then I'd rather not go through the hassle of installing new windows.

This is just for the door glass. The windshield on the truck is fine, and so is the rear glass. Any thoughts?
