Removing Corrosion from Skins
Happy holidays to all. I'm wondering if there is a way to get the corrosion off in the attached pic. I've used Nuvite F9 to repair/remove scratches and gouges, etc. on the front end cap. Huge improvement, but can't get all the corrosion to come off that is between the AIRSTREAM name plate and skin, and the front window rain gutter and skin. Woulnd't be concerned if it was limited to just being underneath and could be hidden. Unfortunately, the corrosion migrated outward and is visible even with the name plate and gutter back in place. I noticed some of the corrosion under the name plate has been completely removed and now you can see the nasty pitting. But, at least it's shiny and looks a lot better than the black corrosion. Running my finger across the black corroded areas around the window gutter, I can tell that it is raised. This is after hours of polishing. I tried sanding with 2000G wet/dry paper in a spot that will be hidden. That brought the area down flat, but still some corrosion in the pitting. The sanding marks didn't come out after about 5 passes with F9, so I haven't continued with that method. Any ideas on how to improve this?
I'm considering "framing" the AIRSTREAM name plate with some alclad that will stick out about 1/2" or so from the nameplate border to hide the pitting around the perimeter. Also considering fabricating a new window rain gutter that will sit about 1/2" taller than the original, which would hide things.
