Old Man with a Hat
I am not a fan of POR since all it really does is cover up live rust. How long will the rust stay in suspended animation is the question. I always kill rust where I find it using a converter like Picklex 20 on cars while I use Ospho on the USS Hornet. Once neutralized I then use my epoxy primer on cars and red oxide on the ship. I tried POR on the deck of the ship 18 years ago and had rust show through in 2 years. This past Saturday I covered a 40 sq. ft. deck with a good layer of Ospho. Just saw it at 11:00 am today and all rust is now black specks. Primer this Saturday.
