First of all, shoutout to Phil at dd, been a big help in the past few months.
Anyway, something slung up on my paint, maybe tire shine, maybe road crud, not really sure. Anyway, I did the typical "eh it'll clay out". Well to my surprise it didn't. So I went to hand polishing with menzerna super intensive. Nothing... Tried simple green (yeah shoot me for putting that on my paint). Nothing...
My next step is wet sanding with 2000 grit. Just don't wanna go there yet. Ideas anyone?
PS, I have sonax PNS on the car. Could something have reacted with that when it was still curing?? Additionally, it stained the XPEL ultimate film, in addition to bare paint (film I understand, paint I don't...)
