Screwed up my vinyl need help...

Howdy,

I sure pulled a bone head move. I had my boat in the driveway working on it so it was uncovered for a couple days.

While it was uncovered I had to do somw welding and metal working in my garage on another project, long story short the powdered metal in the air from grinding landed all over the vinyl, I didnt knwo it had happened until all the metal dust started to rust leaving my white vinyl looking like it had orange freckles.

I have tried magic erasers (went through 4 boxs), pristique cleaner (with stiff scrub brush), I even tried CLR on a small area.

The vinyl is very clean right now but the rust stains persist, please any info will be great.

Also unrelated, whats the best way to get the lake water "bathtub ring" stain off the hull?

Thanks
