IMO the "on coatings" use-case is explicitly pointed out on the labels, because as a general rule of thumb, you're not supposed to top a coating with any other stuff, as almost everything will just...
Honestly, I can't recall having read that anywhere prior to this. Not on forums, and not on manufacturer labels. Then again, maybe we're visiting different forums or using different products.
For one, I've never seen a freshly coated car getting any visible damage from getting exposed to moisture in the first 24 hours after application, even not at the level of morning dew covering the...
There's always a lot of dust in the air (unless you're working in "cleanroom" environment). The only difference is that you see it less inside than outside, because of the lightning and the color of...
That's virtually impossible, unless you're using it on a rotary buffer and you keep buffing at the exact same place for minutes, without moving the buffer even a tiny bit. Glass is extremely hard,...
Most compounds, cleaning agents, detergents, etc. will not work as intended (or at all) close to freezing temperatures. They will not get activated, will not dry or cure in ample time, or will not be...
Distinctiveness Of Image. It is used to measure the "hazing" of the surface and the "blurring" of the reflected image. Subtle hazing won't necessarily effect the overall amount of gloss (as measured...
There's no "dimension" and "depth" to gloss. Gloss is by definition the specular reflectivity of a surface, and only that. That said, the human perception of reflection and "gloss" as in layman's...
That's not required, but might be an effective and cheap way to remove it on a larger surface which is easily accessible and can be or even possibly should be flattened anyway. However, that's...
You need to sand _after_ you've applied the touch up paint to the cleaned surface. If you do not sand the touched up area flat, then the touch up paint blob will drop a shadow, and the defect will be...
That "color" will never "pop" like other colors or black do in full sunlight or when lit directly by strong lights, because the silver base color reflects too much light anyway, and because it...
I'd try to use a tooth brush to remove most of the dirt, then follow up first with an APC, then with an acidic cleaner to remove the remaining corrosion, and then finish off with a metal polish. If...
In my experience, it all depends on how often the car is cleaned. If it's been neglected for years, you can pick up a lot of contaminants on all over the car. If it's been washed regularly and...
There's definitely no point in "arguing" with someone if your only "argument" against what he said is that "he has a PhD in chemistry and a 10,000 sq. ft. lab". If you can't attack the argument...
Because you're living in a moderate (or even relatively cold) climate, you can use essentially any of the three of the mentioned product types. If you'd live in a warmer climate with more sun, then...
No it does not. A "baggie test" is
1. not objective,
2. has no defined granularity,
3. is not even repeatable (not even by the same person on the same part of the same car, let alone on...
"Contaminants" is a very wide term, which includes anything from simple dust particles through shards of metal and blobs of tar that might land on the cars surface or hit it with significant...
Well, this one is a tough one, because for one it's hard to measure and compare most stuff related to this objectively. The problem is, that on ceramic coated surface the apparent level of...
So is for everyone else, because only the person who painted the car (or programmed the machine painting the car) could possibly know how much product he has applied, and what the solvent/solid...
The only two drawbacks of leaf blowers are:
1. that they're a rather large and relatively heavy instrument, and because of that you're always risking hitting the paint with them, and inflicting some...
