Solder question

I'm considering using bending some 60/40 rosin core solder I have laying around into simulated window gaskets for some odd shaped cab windows to help conceal some gaps bewteen the window and the window opening of my model. I already tried bending brass wire, but the solder does a better job of conforming to the window opening curves.

My question - at room temp, will the rosin leech out from the solder over time? Could this ruin the paint or etch/fog the plastic windows? Will solder even accept a coat of spray paint or an adhesive to bond it to the window opening? Thanks for any suggestions or insight.
