another topic for another question. We recently found a small spot of corrosion on the inner part of the hull on our 435, surely caused by electrolytic effects, enhanced by the face that the surface where this small "escavation" has took place has been for a while under salted water (few cm). The area I am referring is the one immediately forward the engine vane.
Any suggestions on how to face this issue and block the process (assuming that the original cause of the problem is not happening anymore). For example, aluminum soldering to fill the small hole, or marine plaster indicated for aluminum applications.
Thanks in advance for your kind reply.
