Staining from roof
This isn’t just a Class C question but there’s not a General category or the like.
2004 GS BT Cruiser. Fiberglass roof. Cab over is hard shell, I assume fiberglass.
The roof and/or cab over shed a white powdery substance when it rains. It is especially noticiable on the windshield. Washing the roof works short term. I’ve used Dawn as well as a citrus heavy duty cleaner, and lately added vinegar. Regardless, after a couple weeks, the staining recurs. Windex doesn’t do much to clean the windshield but adding vinegar helps.
Any thoughts as to what I could use to seal the roof/cab over after washing or maybe another solution?
Thanks
