Hi Everybody,

I´m from Portugal and i´m new here.
Recently i had a big problem in the condenser batteries of some rooftops.
The environment is very agressive (wet and a high humidity) and the fins of the batteries are completely rotten (i broke the fins with my finger and without pressure).

I hear there are a kind of protection we can put in the fins and they give guarantee during some years. I think is a RC Group product.
If some of you know this material or have some solution for my problem, please help me.

Thanks in advance,
HP
