Please forgive my ignorance

I own a window cleaning business and I was thinking of adding WT to my list of products & services

Now I noticed that the people who have shops mostly talk about auto glass is that right?

If so do I need a work shop for commercial and residential properties? (flat glass)

As I figured cutting film at the customers place would be a challange

you need a place to keep your film and at least one table with maybe a glass top. if nothing else, a spare room in your house would suffice.

we cut right out the box on the job site
