I've always wondered, how does the surface of a cd compare to clearcoat softness.



What i mean by that is all are cds super soft, like a bentley clear, or medium softness, or what?

As best I can tell most "average CD"s are softer than most automotive clear. Somebody here *has* to know a lot more about it than I do though...



IIRC some CDs are generally softer than others; maybe it's CD-Rs that are very soft...something like that :think: :nixweiss
 
IMO, there's very little difference in hardness of CD plastic. There are a couple of brands that are marketed as having a really hard clear plastic, and the reviews I've read of them are that they are, indeed, *really* hard, but they are also expensive. I *think* I remember reading that all the other CD manufacturers use the same clear plastic, but the recording media *does* differ between brands.



I do a lot of CD and DVD polishing, 'cause my kids are young. I really can't tell a difference in hardness between any CD and/or DVD brands, and I think I've polished them all.



Anyway, IMO the hardness of CD plastic is that it is harder than Bentley clear,but not by a lot. Maybe closer to Honda clear.

Ah, that's helpful :xyxthumbs So there must be a few clears out there that're considerable *softer* than the average CD, huh?

Unfortunately, yeah, I'd say that's right. The CD test isn't infallible, but at least it's a good gouge. (if there is such a thing as a good "gouge" in detailing...)



Edit: BTW, if you guys have a CD or DVD that is scratched to the point of affecting it's usability, M105 makes very fast work of CD/DVD scratches. Just be careful you don't heat up the disc to the point that it warps. PFW works very well and doesn't heat the disc up nearly as fast as foam.

Huh, I wouldn't have thought to get that aggressive :think:
