It is a thick, tough coating which helps to resist stone impacts. It’s been around for decades.Is that "floor" as in ageing car floor which has, or will have, rust on it?
I've never used anything labelled "stone chip" and I'm not 100% what stone chip claims to do. My own view is that if we are talking of what to put in direct contact with metal, then it has to be a rust-inhibiting primer, my own strong preference being zinc phosphate.
Yes, but does it also do a fantastic job of concealing the rust which is going on a pace underneath it? Think so. Great when you're selling a car.It is a thick, tough coating which helps to resist stone impacts. It’s been around for decades.
What do you mean by unstable? If you mean it peels off, well yes cos it's sitting on rust.I use raptor which is a 2k textured stone repellant. Most single pack stonechat are fairly unstable like a thick primer and as such, you would do well to put a top coat on it.

Quite possibly but then don’t buy a car that it’s been used on and you’ll never get stung.Yes, but does it also do a fantastic job of concealing the rust which is going on a pace underneath it? Think so. Great when you're selling a car.
Absolutely; would regard stone chip or any other black goo as very suspect, unless there was evidence around about what went on before it. Isn't stone chip another term for what used to be called underseal?Quite possibly but then don’t buy a car that it’s been used on and you’ll never get stung.

Looking at the can it says “fine textured” and also says “overcoatable” so yes, you can paint over it.
Unstable in bodywork terms means it doesn't cure so various chemicals including petrol can soften it and breach the surface. Water can also penetrate it and promote rust in the substrate.What do you mean by unstable? If you mean it peels off, well yes cos it's sitting on rust.
Is it designed not to cure, so retaining flexibility to cushion impact?Unstable in bodywork terms means it doesn't cure so various chemicals including petrol can soften it and breach the surface. Water can also penetrate it and promote rust in the substrate.
I have two cars of over 20 years old and neither has underseal or stone chip; I don't go rallying. Looking at the paint, it's very easy to see where any rust is getting started, and very easily remove the surround paint and get back to bare metal. For underseal, think conceal!
Well, I think the bodywork profession is a very small world and so the way you choose to use words has very limited consequence. I didn't dispute your comment, simply asked for further detail. I think that in the world or paints or polymers, probably run by well-qualified scientists, working in multinational laboratories across the world, the term "unstable" may mean something different from what you might think it does.You asked me what unstable means. I answered your question. I've been in the bodywork profession for fourty years. I know what I'm talking about.
