Hi,

My builder has wrapped my pressure treated porch posts with aluminum
cladding. This was just over a year ago. Now the aluminum cladding is
being eaten away at by something in the pressure treated posts.

My question is: I like the aluminum cladding look on the porch posts and
would like to know is there anything that can be put in between the pressure
treated posts and the aluminum cladding to stop the corrosion?

Thanks!
