Hyperbole means exaggeration!  It is a good word to know as you hear hyperbole all the time, and smart people recognize hyperbole quickly.  It is not just a little exaggeration but overkill!  If I say my phone bill is more than my rent….that would be hyperbole!  If I say “my car coating is harder than a diamond and it can’t be hurt with a stone chip” would be not just hyperbole, an exaggeration, an overkill, but a lie!  Don’t be suckered with the common hyperbole of the car coating, car detailing industry.

What others in the car coating industry say has little meaning to me…usually I could care less what our competitors are doing.  I prefer just to do the best we can, concentrate on our work and success will come.  We have been successful.  But, so many customers come in and want to know and they ask; “how hard is your coating?”  Is it 7H or 9H?  

empty-promisesOne can tell pretty easily that the “hardness” issue is the new hyperbole, exaggeration.  “Will it stop stone chips?”  “Of course, the salesman promises.

“Will your car coating take a door?”   “No problem” comes the easy answer.

“Will your coating prevent damage from key thugs?”  “Our coating has tested harder than steel, so no problem.”

We hear these questions and some customers seem to believe this hyperbole.  I think the reason they believe it is that so many car coating/car detailing companies are saying it.  If a lot of people say it, “must be true!!!”

A True Test:

Recently I said to one customer who was telling me that XXX can stop stone chips and protect against a key thug:  Did you ask the salesman to let you try a key on the Honda?  I mean, if it really works, it must work...Can I try  with this key? If the salesman lets you do this, I will shoot myself.

Technical Explanation about Car Coating Hardness

Pencil Hardness Test is perhaps the silliest test to give a car coat.  What does it have to do with pencils. Other tests would be much more important that a pencil hardness test:.Other tests are abrasion, reverse impact resistance, direct impact resistance, cross-hatch adhesion, oxidation, gloss retention, UV resistance, yellowing, blistering, drying times, chemical/solvent resistance (using both the rubbing and spot/time tests), salt spray resistance, humidity resistance, acid and caustic resistance, the VOC and HAP contents, and so on.  What about these tests?

Just think about it, if my coating yellows, blisters and is made up of VOC…why would I want THAT on my car.

Let’s look at the pencil hardness test

pencil hard2:

The idea of the test is to take a pencil 2B, 5H or 7H, put it into one of these machines and run the pencil over the surface.  If it scratches the surface, then reduce the pencil “hardness” accordingly.  When it doesn’t scratch, you have the hardness!  Right???

What if it isn’t a pencil but a knife, and the knife isn’t rolled back and forth lightly in one of these machines, but stabbed or slashed at my car…with violent force!

Will the coating protect against the knife or the key applied with force…not just a little weight that is rolled gently over the coating.  So, don’t shoot me folks, the pencil hardness test is a joke as the likelihood of someone rubbing a 9H pencil gently on top of your car coating is a nonsense test.

You can see how weak and ridiculous the test is,  Think the stone chip flying off the truck at 90 will be so gentle as this pencil point rolling gently on the paper.  Get real,  click to play

Finally Point about Car Coating

Car coating is better than wax!  Second, when dealing with any car coating company, read the guarantee!  The XXX company will not guarantee it (in writing) against stone chips.  If they do, I might even give them a try, but they won’t.  They might not mention it or they will most likely exclude damage done by stone chips.  If fact, before you go for a visit, check out their guarantee.  If it reads like a lawyer document and gives you a quick headache, avoid that shop!
