It's a special kind of paint that most boats have under the water line. Not always red but that's very common. It's called ablative bottom paint. Ablative means it sheds over time. The purpose is to prevent fouling on the underside of your boat when it is in the water for a long time. All sorts of things like to grow underwater by attaching themselves to any surface they come across. On the underside of a boat that looks ugly, slows the boat by increasing drag, is a bitch to clean off, and can even compromise the hull if left unchecked. Hence the special paint that gradually sheds to self-clean.
Yes and no. Pettit, Interlux, and many other manufacturers make a hard paint. Ablative does no good if the boat isn’t moving, or moored in a current. Ablative should only be used on trawlers and sailboats. Kinda pointless to use an ablative on a boat that routinely planes out… The paint would be gone in half a year! 19/20 boats here use hard paint. Ablative paint “hardens” Out of the water and loses its ability to shed the particles that remove growth. The boat has to be launched within a week or so. Barnacles can go right through all paint if they aren’t physically removed- they root into the fiberglass hull causing the osmotic blistering by making a path. Gelcoat and resin are naturally porous so water can enter the substrate, but it cannot travel out because it is building pressure. As more and more water migrates into the fiberglass layers, it spreads out and builds a void in the hull (the blister). The water then begins to break down the polyester resins (which is why epoxy and vinylester resins are superior). Blisters can migrate entirely through the hull and cause a boat to sink eventually…
We have several cats that run around our local boat yards in Tampa Bay, with a hell of a lot of bottom painting going on. That includes the dust left behind from the sanding and sandblasting. There aren’t black, blue, geeen, red, and brown cats running around, and I’ve had those dumbasses come up to me while I’m balls deep in glass dust from grinding out blisters. The cat would die from the toxicity of the dust and other common boat yard toxins (like used oil, grease, styrene, MEKP, antifreeze, lead, etc…)long before it “changes colors”.
That being said, in other countries they can use the bottom paints our military uses- ones we used to be able to use in the states. They have a very high copper content, among other metals. Many east coast boaters who have the ability will incur the extra cost to travel to the Bahamas to use the “good” paints outlawed here. For example - Sea Hawk paints, located here in Clearwater, ships a significant percentage of their high metals paint and additives specifically to Bimini for the American boaters.
Fun fact, some assholes think it’s a good idea to put capsaicin in the paint thinking it limits growth. IT DOES NOT. IT DOES REALLY, REALLY PISS THE GUY OFF THAT HAS TO SAND IT. That causes a miserable couple of days for the poor guy because not only does the bottom paint get into pores and cause inflammation, the capsaicin gets in there to and really inflames everything, even leading to bleeding through burning sores. Loads of fun…
TL;DR, it’s not the paint. The cat would be long dead from the toxicity if that were the case.
I use to have a cat that looked like that. Her skin was pink and she had pure white, well groomed fur. She had blue eyes though. She died about a year ago from lung cancer. Her name was Judy and she was my friend.
Too bad it didn’t quit smoking catnip sooner. I miss our cats. They were assholes, but entertaining assoles… We had a gook Vietnamese neighbor that ran a crack motel/ official Pinellas halfway house next to us who decided to get rid of her rat infestation with poison. Almost all of the neighbors cats were dead in weeks. I hope that bitch ate a few of the dead ones and got sick herself…
