Finished the one I was dreading the most: the vent tank cover. The PO started breaking it in the past, and I finished the job when I removed it last year, so did more of the ABS cement and fiberglass to repair it, and patched up a few other holes and cracks at the same time.
Since it's getting wrapped and I'm not too concerned about what the panel looks like, I also wanted to test a restoration option: acetone. It brought back the shine and color to the shock tower trim, and did the same on the backs of some plastic panels. I did a fast, light wipe of the panel with a paper towel that was soaked with acetone. The results were surprisingly good. I don't know if it'll hold up over time, but for anyone looking for a super fast, easy fix, it's something that might be worth considering.
Wrapping was a tough job. 4+ hours for the whole thing. I ended up cutting 3 seams into it but tried to keep them in areas that aren't easy to see; someone who's better at this could probably do it without cutting. There's also some wrinkles that I wasn't able to get out but those too should be in hard-to-see places. The face of the panel looks pretty good, though! Hopefully I can get it back in the car easier than it came out.
