Looks like new!
Tricky to apply with the finger but you soon get the hang of it. The harder you press it in when applying the better the result. I was a bit worried as some got onto the window and paint but even after the recommended 30 minutes it just polished straight off. To play it safe you could always use some 3M tape.
Wow! The rubber looks like brand new. The windows are operating smoother too. I also used this around door and boot seals with great results.
Makes a huge difference to the overall appearance of the car in terms of the clean and detailed vinyl/rubber lines. The rubber looks and feels healthy.
Another tip: apply in one direction only for best results and when you wipe it off then again use one direction only. This avoids the problem of patches.
