So I'm in need of some help here. I left sap, as well as those helicopter things from maple trees sit on my car too long and now I have major etching all over my hood, roof, and trunk that I can't get off. Most of it isn't rough to the touch either, it's pretty smooth on the paint.
Here is the link to the pics, sorry that they're not that great. Car is also a 2014 plasma blue WRX.

Things I have tried so far with not much luck:
- claying some spots (seemed to help after after a lot of work on one area, but it scratched up a little)
- polished with M205 on light cutting pad (helped a little but not much)
-isopropyl alcohol (also helped a little but still left quite a bit, while also scratching the clear slightly)

I have no idea what to use next/how to approach this and I'm starting to get worried. Would next step be compound and heavy cutting pad? Any help would be greatly appreciated! Thanks!
