I've a motorhome w/ painted metal side panels. The hex-head screws that
secure the panels are beginning to 'drip' rust down the panels. Said
rust isn't TOO bad at this point. Is there any way to remove the rust
stains without destroying the underlying [white] paint? (I'm going to
replace the rusting screws and either either seal them with clear
sealant of some kind, or cover the screws with 'caps.')

THANK you for any advice!
