When working on scenery, move rolling stock before proceeding. I use rubbing alcohol as a wetting agent. Sometimes, you don’t move rolling stock before spraying and you get resulting white spots. To fix, brush the dust off the roof, then respray with Dullcote.

Nice simple fix.

I will keep this information filed away. Hopefully I remember it if I ever have this issue.

Yup, just don’t forget to cover your windows with tape.

You just “discovered” my secret to duplicating bird poo on old, or neglected rollingstock.
( something I "discovered by accident myself .)

Well, I do remove my rolling stock and engines (and vehicles and structures, too) but my simplest trick for neat, no-overspray wet water is to use a pipette, never a spray bottle. Application is much tidier and more precise. This is even more effective when ballasting, where you don’t need to cover a wide area, just a narrow strip.
I never use a spray bottle when ballasting. The only time I use one is when doing a large area. I just have to not be lazy and move motive power and rolling stock off the area I’m working on.
