Had the same on my 5th gen. In my case, the lower door panels started rusting from the inside out due to water and salt sitting inside the door seam and not being able to drain properly as well as not enough wax sprayed into the seam.

At first it is bubbles, eventually it will show its ugly face. Painting the hood will last longer when done correctly. The doors though will come back because there is no way to remove or inactivate all the corrosion in the seam.

I did both 4 years ago, hood is still fine, rust on doors came back and I just redid it this year.

I have no rust at all, just the bubbling and the paint falling off.
