Glass Coating---what is the standard practice of coating customers glass?

As title says---When coating glass, do you just do windshields or do you tend to coat all glass--sides and rear?

On my Xterra, I coat all the exterior glass. If I had a paying customer, I would do the windshield, rest would be extra.

If the customer is paying for it, I coat all windows. Often I will give a complimentary windshield seal using some extra sealer I have like Chemical Guys M-Seal or if I have some RainX around for some reason. It doesn't cost much or take much time and I tell the customer that I put some "super RainX" on their windshield. Always gets a positive response.

Just the windshield. It's pretty much a waste of coating to do the sides and rear. On the sides and rear I use Wolfgang Perfekt Vision Glass Cleaner which cleans and leaves behind a Rain-X type barrier.

Coating the rear isn't a waste, I love when I do mine. Easy to see out.
