I never ever try to finish out with rotary ...
Trust me I used to say I "jewel" paint until a customer knowledgeable on paint came back 2-3 months later after many washes and sure enough there was some light marring and holograms..
This is my experience also... after time goes by and the paint is washed enough and then inspected in full, overhead sun, if there is any hologramming, light or heavy it will show up and a knowledgeable customer will know where it came from.
I now just use the rotary for corrections and gel coats and finish out with the flex 3401
Change the action of the tool
I agree and this is what I always recommend to people if they want to ENSURE there are no rotary buffers swirls or holograms in the paint simply
change the action of the tool. That is switch to a tool that both rotates and oscillates.
To me, and this is just my opinion, if you want to ensure 100% you're leaving a 100% hologram or rotary buffer swirl free finish then for your last machine step change the action of your tool by switching over to a Flex 3401, PC style polisher or even the Cyclo Polisher.
Time-proven remedy and insurance.
I didn't really try...when I was done with the rotary I pulled the car in the sun and saw no holograms....
Pulling the car into the sun isn't enough, you would have to first chemically strip the paint in order to accurately inspect. This is the part that most people don't do and if you decide to do it you're going to risk marring the paint in the process PLUS it's going to
ADD time to the job.
theres a bunch of folks that finish down with a rotary on here
I've been hearing and reading this for decades... what I
don't see is where they describe in detail their process of chemically stripping the paint to prove they left the paint
100% hologram free and all the before and after pictures that back up their words.
It's not always about how GREAT the detailer is it has to do with both the paint and the fact that you have a pad rotating in a single, circular motion on a material that I describe, as do others as scratch-sensitive.
The combination of pad, product, pressure and rotating action imparts it's own mark into the paint, even if it's incredibly light or shallow it doesn't matter as it will show up over time on dark colors.
Also, if you're finishing out on a white or light colored car with only a rotary buffer that's a lot easier to claim 100% swirl free because it's a lot more difficult to inspect
and see after chemically stripping, (which I still never see anyone documenting), unless you really work at it.
I posted quite a bit about this topic here and no one ever challenged it...
How do you stay away from holograms?
The true test is always black paint, doesn't matter if it's single stage or basecoat/clearcoat as black will reveal everything. The point being is if hologramming is taking place on black paint then it's taking place on all paint it's just that you're eyes cannot easily see it.
