top penthouse bolts rusting and rust around roof lights
I've got a 2005 Ford e-350 with the penthouse. I've got 2 rust related issues.
1. the top bolts on the penthouse are rusting out. They're on the exterior of the top of penthouse. It looks like they originally had a cover on them but only a few still have that. Is there a diagram anywhere detailing the penthouse top? I'd like to know what I'm getting into before diving in. Also, I assume the best replacement will be stainless equivalents.
2. The 5 or 6 exterior lights on the chassis above the front windshield have a little rust around them. One, in the center of course, is blistering around the light holder and needs to be ground out patched and painted. The others with early rust will be cleaned, primed and painted at that time. I'm afraid this is a body shop effort. Should I decide to tackle it myself, is there any magic paint/primer that stops the advance of rust?
Thanks for any thoughts on the above.
