Have a friend that has a home by the ocean ( Marlyland). He wants new siding and pvc coated aluminum coil. I have heard from a few guys that pvc coated aluminum degrades in the salt air by the ocean and they insist on using painted aluminum coil. Any of you guys have an opinion?

I've seen PVC coated coil go in as little as 4-5 years. Hemming the soffit bend helps, but is not a cure.

Painted coil does better, due to it being finished both sides.

All aluminum coil will corrode in salt air eventually.
