Holograms

Well, it seems that the last couple of times I have detailed cars I end up creating Holograms (on dark colored paints). I believe it is coming from the SSR 2.5 with a green Sonus DAS pad. Any thoughts on how to prevent and remove holograms? What causes holograms in the first place? It also seems that they are created on the lower portions of door panel and on bumpers. Thanks!
 
I would say it's more likely that you would cause them on the lower panels for two reasons. One is it's slightly more difficult to hold the machine perpendicular to a vertical and/or curved surface than a horizontal one and second, because it's harder to hold the machine properly, you're not working the compound long enough. Are you using a pc? Sounds like you're getting hazing from not working the compound long enough or you're inadvertently using the edge of the pad and causing the holograms. Never seen that done with a pc though.
 
Holograms are fine scratches oftentimes induced by improper use of hi-speed polisher.Improper use will include using dirty pads, too agressive polishing compound at very hi-speed. The bottom line is your polish has to good, so is your pad, and run your hi-speed polisher at between 1000-1400RPM. Do not go higher, instead make many quick passes or slower passes with porter cable orbital polisher. PC that fails to break down well a polishing agent will induce marrings and holograms. To fix the problem, use Menzerna Final polish2 or Optimum polish on a white or orange power pad, run your machine at 1200 rpm make vertical and horizontal passes work the polish in, and wipe to assess your progress.
 
I use a rotary, so it may not count. But, fwiw, I get holograms with:
1. Wool.
2. Wetsanding a dark area that needs a lot to make it come back.
3. When I try to go too aggressive with improper "chase out."
4. Dirty pads.

Almost always I can do a medium aggressive polish (like SSR2.5) with a polish pad (I use Green Edge) without holograms. If I get some breaking of the light, I follow with a lighter pad and SSR1 or Farecla G10.
"Chasing Out" means making sure you follow more aggressive treatments with lighter ones.
Using the rotary, I spread @1000rpm, break in at 1400. On the hood I'll often go to 1800. I move slowly, methodically, evenly.
 
Hmmm...First of all, I use a PC. Secondly, let me describe my typical process for time savings using the green Sonus DAS pad, SSR 2.5, and the PC (on a vertical surface).

1. Apply product to pad...a circle of product
2. Spread polish onto surface
3. Turn PC on at a level of 1 and make a couple quick passes onto the surface
4. Turn PC to a speed of 5 and work polish in until it is nearly dry
5. Wipe off

From the posts above, it seems that I am running the PC too high a speed, right? Probably the inability to keep the PC completely perpendicular to the surface is another reason for my hologram creations.

If this is the case, how would I be able to keep a decently fast pace when polishing to save time? Thanks
 
Is this hologramming or hazing that you're getting? I have never seen holograms created using a random orbit machine. I wouldn't even imagine it possible to create holograms with a PC at speed 5. But, anything's possible...

If the problem is hazing being left behind (which I have seen quite a bit of with random orbit use), you should just follow up with a less aggressive polish after the SSR2.5.

Pictures would definitley help.
 
That's what puzzles me too! People comment that they create holograms when using rotaries, but I uses a PC. I am pretty sure they are holograms, but I have no pictures to show what exactly is the problem as I have no camera at this time.
 
I've seen hologram looking haze left behind from a pc. Again its "wanna-be" holograms which are actually haze.

It happens when an abrasive product is spread and allowed to be "worked-in" some areas more than others. This in the ends shows the trailings of where the machine made its passes. Therefor looking like holograms to someone who doesn't really know what rotory inflicted holograms look like.

I learned a lot from owning a jet black vehicle! :)
