Clear hardness Chart - 06-25-2010, 10:12 PM

Hey Guys.... as a rookie... not newbie... but rookie to the detailing thing. I know we have some really smart guys when it comes to polishing:notworthy
I have seen some really great charts put together explaining pad, polish, etc etc.... would love to see someone put together a chart for hardnes on clear coats on OEM late model cars.... this would really help the new guys in selection of product I would think...

Picture is worth a thouhsand words.

While a paint hardness chart is a great idea, I think it would be very difficult to accurately assemble. An idea of paint hardness is just something that you acquire through experience and can only really be subjectively explained unless it is scientifically compared using standard units of hardness with back to back testing.

How can you accurately compare hardness through buffing without being subjective? It all depends on pressure, polish, pad, machine, ambient conditions. When you add in that paint hardness can vary by year, manufacturer, and even colors of a single manufacturer, creating an accurate comparative chart becomes damn near impossible.

Long story short, this is why a test spot is always advocated.

Great Piont....but for a piont of reference.... something would be nice.... IE... late model Chevy Tahoe to let's say a 1999 model. Thanks...

Wow... what a great idea! I wish there was such a chart. I would sure make my life easier sometimes. :clap:

But unfortunately it's usually trial and error. Start with the least aggressive polish and pad and work your way up until you get the desired amount of correction.

:iagree:

Ron, if you're tight for cash and don't have the money to experiment with different products, M105 and M205 are two products that can tackle damn near anything. Pair those two with a DA polisher, a few LC orange, white, and black pads and you're got a solid start-up package.

Although this isn't exactly what you asked for it does help explain the differences when polishing different hardness paints - .

This and many other helpful articles were written by Jon Miller (aka TOGWT) and are available at detailingwiki.com. The man is a walking encyclopedia of detailing.


Everything I say can be fully substantiated by my own opinion.

Trying to assemble a definitive list of relative paint hardness based on make/model/year would be an exercise in frustration (and probably confusion) as well.

Will a noob to machine polishing consider a particular paint to be "hard" while an experienced pro will see it differently? What about the fact that auto manufactures often change paint systems mid year, or don't use the same paints in all factories?

You end up with questions like this:

But which 05 Benz? What factory is it from? Built in Germany or the US?

Of course, assembling such a list would blow apart a lot of misconceptions regarding specific vehicles. I can't count how many times I've read a comment like "BMW has clear coat that is so hard that you have to use _______ to correct it." In some cases, yep, that BMW paint can be crazy hard - but I've also worked on factory BMW paint that was a breeze to correct.

But the biggest problem lies in the fact that there is no definitive empirical measurement for "paint hardness" as it relates to polishing or leveling of the coating (at least none I've ever found). Yes, there are a variety of methods to measure specific hardness of any material, including coatings (Brinell, Vickers, Rockwell, Knoop, etc) but they all make use of indentation measurements. And applying perpendicular force to a material in a fine point is quite different from trying to level that same material through an abrasive process.

But no matter how you would rank different paints, you've still got that one enormous variable - skill. Not everyone can play a piano like Beethoven or Thelonius Monk..... play guitar like Jimi Hendrix or Eric Clapton.... Or play a buffer like Kevin Brown or Todd Helme.
