I've got a Dodge dually RV tow rig I was working on today, covered in tree sap so bad that I wish I took before/after pics. APC, DX330, Iso- all we're able to remove the sap from the paint with some elbow grease. Clay didn't do shit. But I've got half a dozen dime sized splotches on each rubber window trim; same for the black plastic windshield cowl and mirrors. If it was a few light dots I'd throw caution to the wind and just go to town or leave it as is, but I want to use something that won't stain/discolor the plastics and rubber. Any ideas? It's the rough/orange peel trim and not the smooth/shiny/polish-able plastic; and the window trim is the gummy rubber that loses color with solvents. FML. I'm hesitant to even use the APC with the age of the sap on the plastics fearing that I'm going to screw it up because it's super bonded. The sap is roughly a year old, from somewhere between Minnesota and Pennsylvania. It's not standard New England pine sap, not crusty, still gooey underneath top layer and bottom is rock hard stuck to the paint- never seen it before in my life.
