I have had windows replaced in other vehicles and been dissatisfied. The only problem I didn't have was leaks. They pried against my dash pad in once instance. They hosed the inside of the car down with silicon spray another. They didn't replace the worn out lock strip on a third, and refused to correct that even though they could not put it back correctly.

You should ask around word of mouth for recommendations or even ask to watch them work sometime before giving the job to a shop. With all the butyl rubber mess involved in these windows, it's likely to be a mediocre job if someone does it for you because they are on the clock. The glass needs to be set at the correct elevation too, or the chrome will be incorrect. If molding clips break during the work (likely btw) , they will be missing when you get it back, and glue holding your chrome down.

Zaino Bros sells a glass polish called Z-12 that works well. Griot's garage and Einszett also sell glass polishes. Don't use steel wool, even though some folks suggest it. Different windows respond differently to this treatment and the damage is permenant.

For cleaning glass, skip the special towels and use an old piece of newspaper with your glass cleaner.

If the glass is badly etched, you won't be able to polish it out. Zaino works pretty well for mild etching and mineral staining.
