Cool to see this new technology. The former methods did work well, but it sounds like ultrasonic methods last far longer.

The New Artic Ships appear to be breaking out into rust. Just look at them. My husband has worked on a lot of old cars in the past, in his experience the paint has to be thick enough to provide a real and true water/atmospheric barrier. This is really the commonsense approach. Some applications of paint, from the factory, are just thin. We see this on a lot of new cars. It is important to understand that when painting metal you are setting up a barrier, blocking out water and the atmosphere. Air that in itself is often saturated with water and airborne chemicals. When painting iron, steel or aluminum you must understand that oxidation is immediate and the metals are under attack even as you work with them, for example building a ship in the shipyard. I think this is all common sense which often is anything but common. PS I also think some great advances in metal preparation are needed before paint is applied. Sadly the paint on the new Artic Ships is just not good enough for harsh conditions, at least by its appearance.

Quite agree , Mary, below the waterline I believe is fairly well covered by Anodes , both passive and active , Above waterline the best answer is careful application from initial build ,and constant maintenance of appropriate finishes thereafter due to wear and tear. Waterline is by nature the most difficult to police , whereas bad design leads to pockets that are inaccessible for regular maintenance throughout the vessel.. You can't beat old fashioned common sense and regular upkeep combined with quality materials. Unfortunately, money is god these days 😪

You get out on a cat with rust-stain remover and a longtom. That's how we did it in my day. :)

Yup

50 years after steve jobs made the microcomputer, I heard the Canadian warships are now using them.

Four words, Electric current rust protection.

[@robertskolimowski7049]

Ok, coming from a complete novice, isn't there an efficient enough method to prevent rust from forming in those naval ships in the first place? 🤔

[@YaMomsOyster]

Yeah, build them out of Wood…lol But I agree

[@MrCanuck78]

We have had rust preventing technics for decades now , this makes our navy look weak ! lol . smh

[@blowinkk9396]

Our navy is weak. look at what they have been given to keep us safe. They have no hope in hell

[@MrCanuck78]

@@blowinkk9396 most Canadians know this but it still shouldn't be prodcaste to the public lol.

[@blowinkk9396]

@@MrCanuck78 Lol oh the public knows. All they need to do is look at any of our navy ships, let alone our sorry submarines. How about the billions wasted building 1 new ship at a ship yard that is known for building bad ships?

[@Rubin250]

They are rusty because they are old. 🤦‍♂️

[@maryrafuse3851]

The new ones are rusting.

[@eanerickson8915]

Protect us from rust. LOL. Do our navy ships protect us from Russia or China?

[@blowinkk9396]

You can't even build ships for our navy so now your going to waste more time and money? Great...
