well, before I left the trailer yesterday I tried a small area with the spray nine and it did what I hoped it would.. removed the black, if done by hand with a microfibre cloth. when tested on a larger area by spraying on, wiping and then rinsing .. some of the white finish came off, not much.. but some did
looks like i'll give your mean green a try.

or not.. back to my original post. my trailer is metal sided
.. not fiberglass. so it seems we're comparing apples to oranges.
looks like bc camper stated what the key is.... use a rag/cloth/towel .. wipe, remove. do not spray right on the finish
i already have my finishing wax.. i'm either going to use a carnuba liquid wax that I have or an aerosol carnuba wax called fukken wax. my issue is the black marks being removed before wax.
thanks again for the input
