Holograms

Holograms can be installed by hand. They can be caused by anything that will impart groups of very fine parallel grooves in a finish.







PC.
 
I see what PC is saying, however I think there would be a much different look / pattern to hand induced and rotary induced marks.
 
Absolutely LightngSVT, holograms from a buffer will typically have patterns that are different from hand induced holograms.



There's no "official" definition of holograms in car finishes (or of anything else in the detailing world) so anybody is free to use terminology any way they want. Some will insist that they are only caused by rotary buffers or whatever. They are free to do so.



In my book if it looks like a hologram and acts like a hologram then it doesn't matter how it got there, it's a hologram. To me, that's any paint defect that has that "3-dimensional" look to it. In other words, if it creates a virtual image that appears to "float" above or below the surface or to "move" when you look at it from different angles it's a hologram.



The effect occurs when the pattern of a swirl is interpreted by your eyes and brain as a stereo image. When we see different images with each eye that appear to be the same object from different angles our brains interpret them as a single 3-dimensional image. Whether it is in fact one thing from two angles or two different things that look nearly alike we will perceive it all as one.



Images created by groupings of parallel grooves can be perceived this way if they are structured appropriately. It doesn't matter if they were made by fibers spinning on a buffing pad, grit particles dragged along by hand, fibers of a paper towel, a CNC point mill or anything else.



If you really want to get into the technicalities, here's a great article about it.





PC.
 
I would say that holograms are pretty exclusive to the rotary polisher.



I can see how *marring* could occur from using an improper applicator, washing technique, etc.



How would you go about inducing holograms by hand, based on your definition?
 
Hologram

Noun



1. The intermediate photograph (or photographic record) that contains information for reproducing a three-dimensional image by holography.

Again, maybe it's just me, but I say if it looks 3-dimensional and acts 3-dimensional it's a hologram and it doesn't matter how it got there.



To make them by hand, on a car, with a paper towel read the article, paragraph 1.1.





PC.
 
Interesting, I would just call that marring. I guess we should have hologams and buffer holograms.



I just don't think you'll read too many post that state "well I got some holograms in my paint while polishing by hand over the weekend, how do I fix this?"
 
The reason I asked was that I don't have a rotary or a PC but I noticed at the weekend that I've got a hologram on my passenger door. It looks like the work of a rotary.



I was just wondering whether it's something which I could have caused.



Bear in mind that this car is 6 months old and I'm the only person to have ever cleaned it.

You'd be surprised what is buffed and "corrected" on new cars before you take delivery.



This car was brand new when I detailed it. The owner brought it to me because the "paint looked weird."

I always thought you can get holograms by buffers only but ive seen holograms by hand. I had a PDR guy use rubbing compound on a black car by hand to remove knockdown nylon residues, I didnt notice it until it was in a certain angle days later. Sure enough it had a 3d effect and was very light, dont know if they are "officially" holograms, but it sure did look like it. :idea
 
Fixed a friend's car a couple weeks ago, he hand installed swirls using Turtle Wax Rubbing Compound to remove some branch scratches down the entire passenger side of his car. Not quite buffer holograms, but pretty damn close. Using a PC, I removed the swirls using Meguiar's #2 (new orbital formulation), did the whole car with #9 and then #7, before topping with #26. Looks like new.
