An F360 Spider, as in Ferrari F360?? Yikes!!!!!!!!!! No wonder the concern.
If it`s on your cloth top, is it also on your paint/clear-coat??? I assume the top color is black and not tan.
Do you have a Ferrari dealer nearby that you could inquire about this problem? Not sure if they would tell you how to do-it-yourself and most likely will suggest bring it in and we`ll take care of it for you for a "nominal fee".
Or are there Ferrari forums that may have other (better than mine) suggestions for cleaning this specific top problem??
I know RaggTop makes a cleaner specifically for fabric tops that Stokdgs has used and I have, too, but that is mostly for embedded road grime and dirt, not sap.
Whatever you do, let us know.
I myself, along with long-time Autopian contributor Accumulator never posted pics. I would not be that concerned about the pics, although as someone has said, "without pictures, it never happened" and the proverbial "a picture is worth a thousand words", which would explain my many times long-winded posts.
