Just a update, I totally think the project is worth it now. The minor runs and minor flaws are barely noticeable. People only notice them if I point them out.
On a side not, the 3M spray was put to the test the other day. I was driving to work when all in a sudden a big chunk of wood flew into my lane and hit my bumper while driving ~72 on the highway. It happen instantly so I was not able to swerve or slam my brake. I estimate the piece of wood to be 10'' long by 2'' wide by 2'' thick. Apparently, the chunk of wood originated from a 4''x4''x 6 that was in another lane. The 4''x4''x6 was beat up good on one end which led to many pieces of wood littered all over the highway.
Anyhoo, if you look at the picture, you can kinda see slight angle that the wood flew at my bumper. The area is opaque and the 3m protect ant has lifted off my bumper. I suspect that there will be minor damage that a good buffing would take care of (after removing the 3m). I will update whenever I plan to redo it in a few months.
It just rained so the scuff don't look to bad.
