Sorry to hear of the loss of your dog. Sometimes they are almost human in the way they communicate and show personality trates.
My dog is a Chug. As in chug a beer. It is Chihuahua and a Pug mix. I have the short hair version. I think she is 3 years old.
The tint job was something I wanted to do to the trailblazer I had. Never got around to it. That SUV sucked money from me before I said good bye to it. Funny thing. I thought that was a truck. No not at all. At best a school bus. I couldn't slide under it. The ranger I can slide all over under it without worry of getting close to anything. That is helpful.
I am going to post the tint video I watched. I didn't heat shrink it. I did the rest of the steps.
I had to remind myself to take time and have patience. You can do it. The Ranger windows are small compared to others. Like the Scion in the video. I did my cuts on the truck. Did not use a sharpie or cut on a different piece of glass. Thank you for the comment on my health. That means a lot.
