Remove teak vents and replace with AL?

or

Remove and strip teak to bare wood and build up a few coats of CPES on it. Unlikely mold will grow there any better than AL.

The one with black mold growing on it is aluminum.

We are working on a house crawl space that has some mold starting.

The local contractors use both Rustoleum products , one after the first has dried.
Supposed to be better protection and smells far better.

Ahhhh. Down here I switch off the ac compressor in my vehicles as I approach home to run air through the system to rid it of condensation. I too have noted the tendency in my last boat for condensation to collect on the AL louvres. Current boat has teak louves, and condensation seems to not be as big an issue.

+1 for Concrobium https://www.concrobium.com/products/mold-control-spray/
Probably not a permanent solution but works really well. Have used it successfully on varnished teak, Awlgrip and my vinyl headliner without any problems.

Ted,
We delt with mold down here in the florida keys after hurricane Irma ( we had 4 inches of salt water in our house and they did not let us back in the keys for a week ). We researched the products available and asked the insurance companies and FEMA what we should use. this is what we found. Bleach was not a good product to use because it kills the mold but the by-product it leaves behind is food for more mold to grow. Products that worked well and we used were microban ( its called mediclean now ), and Concrobium. Concrobium has salt in it so not so great for metal.
