What, if anything can be done to stop what has already started and what can I do to prevent any future areas?
The crazy thing is, I'm only seeing this on the side door.
As the pics show, some is just around the screws while some is starting around the one hinge.
In the past, when the factory fasteners started to rust, I replace them with stainless fasteners the same size and style.
Any suggestions sure would be welcome, it's really starting to look crappy....
Thanks in advance...

Jeff, what you have is basic surface corrosion. The white powdery stuff is the aluminum 'rust'.
Best to remove the paint from around the area to see what the extent of it is in each area,
maybe an inch out from what you can see at each spot. You can either use a stripper (masking off each spot),
or use some automotive type abrasive paper, 120 grit to get the paint off then 220 grit to feather the edges.
See if you can find some Alodine
https://www.google.com/search?q=Alodine ... 8&oe=utf-8 to treat the surface with, then prime, and paint. The reason for the Alodine is to re 'clad' the aluminum,
the coating that most likely was broken during the manufacturing process (it happens), One tip about applying
the Alodine, it needs to be applied to what is known as a water-break free surface. The translates to a surface
where the water 'sheets off' and doesn't leave dry spots with borders. We used to use a light amount of
Comet or some other scouring powder, just be sure you get ALL of it rinsed off.
Hope this helps.
