I used this for the front black leather seats in my 2008 Lexus rx400h. Especially on the driver’s side there were cracks that had began to tear open. This tape worked well, I only wish I had more and that it was wider than 4 inches. I tried to order 3 more but Amazon’s app wouldn’t allow me to because it said the seller only allows one roll per customer. This worked in my favor because I found another Amazon seller who did have 6 inch by 120 inch rolls and I was able to purchase 4 more from them. This type of tape has very good Adhesion on flatter areas but around corners can be tricky. It is fairly easy to use, although scissors work better than an exacto knife to trim. The thickness is enough to provide moderately durable coverage over torn areas but thin enough to be able to blend in without being overly noticeable. If you can trim in such a way that edges meet up with seams or if you tuck the edges it is even less noticeable. Edges that are exposed aren’t bad since the material is so thin, and they could probably be easily hidden further with a leather or vinyl repair kit that has a liquid or paste to blend the edge with the older material. I wasn’t quite that adventurous, I simply wanted it covered to prevent the tears from worsening, I plan to get matching plush car seat covers so I wasn’t too worried about it being perfect. I hope this helps, good luck with your projects/repairs!
