First time getting my car tinted, what should I ask the installer?

Posted by tintproninja@reddit | askcarguys | View on Reddit | 8 comments

Most common questions I’ve seen are:
-What type of film is best for my car?
-What brands do you offer
-How much will it cost

But aside from these, can anyone mention what other important questions a first-timer should ask the installer? I’m also considering brands like Hitek Film, so any insights on what to check or clarify would be really helpful.
