That's really a problem that you'll experience with all beading LSPs - to a greater or lesser degree - unfortunately. The industrial fallout and dust can easily combine with rain water to create either an acidic solution which then etches into the paint, or it can create a lime/cement-like slurry that then leaves hard-to-remove deposits on the paint. Opti-Seal seemed to be better at resisting watermarking than the Collinites, at least IME, but even that got left with a few watermarks that needed a paint cleaner to remove.
