My '65 Formula S is being painted this month. That narrow gutter above the side windows is rusty and using wire and fiber brushes on a drill seem to be only "polishing" the rust a little. Is there a better remedy? Thank you.
I cheap approach is Lysol toilet bowl cleaner ( not the bleach kind). Clean it, dry it then apply. Let it sit for 10 mins, rinse and repeat. I can't emphasize enough....wash it off with water 3 times minimum. Be careful of what touches that stuff, as it will transfer and keep going for days, have a trash bag handy. Try this on a sample to see how it works...realy wonderful on chrome with bleeding rust. Again, clean, clean, clean then WD40
