Ya I've had that same thing happen to me once I was painting my Civic (paint coming off cuz of tape).

I was using this green painters tape that was good for 8 days it claimed. As you did, I wetsanding and painted with that tape on all the time, what a big mistake.

Things to take note of...

1. You better peel the tape off slowly once you are done painting. Because once I pulled, the paint started to rip at every edge where the tape was. Thats why when you look at my edges, some of the paint is stripped.

I still have to final wetsand and final polish next summer so it will be gone by then.

I painted this summer and wanted to polish this summer also, but along came school so final polishing I will do next summer since theres no point as it feels like Winter.

Good luck! Looks good thus far!

2. Dont wetsand, wash the car with the tape still on, its disaster waiting to happen.
