Buffer trails possible with 7424?

Has anyone ever had buffer trails or holograms left behind after using a 7424? I haven't got one yet, I'm sort of afraid to use it for this reason and have worse results than what I started with. I've seen this happen many times with a rotary, but is it possible with the 7424 unless you're doing something really dumb?
 
A DA cannot make holograms/buffertrails. Its impossible.



It has nothing to do with heat either, its the action of the machine that causes it combined with things like not breaking down the product, to aggresive of a pad, moving to fast, runing the machine to fast ect.
 
Yes, with a PC....its entirely possible. Your talking about abrasives, and an rotating/orbiting pad. Why does everyone think its not a possibility?
 
I believe you are/can leave micromarring but not actuall holograms.



The thing about holograms is they are perfect straight lines, how do you do that with a machine that oscilates/random orbits? They wouldnt be straight lines.
 
OK it IS possible, but if you have common sense and some guidance (this forum, watch the AG videos a few times) and are semi-careful, it would be nearly impossible to put buffer trails into the paint. Just make sure you use the right amount of product, and don't put TOO much pressure on the machine.



If you wanted to put some buffer trails in the paint, you might be able to. However, if you're a beginner learning this machine, you have little to worry about. I just bought a UDM and tried it out for the first time a couple weeks ago. I'm a beginner, so I'm pretty slow with the machine, but I have absolutely no fear that I'm going to damage the paint using OP and an Orange LC Pad (currently my most aggressive combo).



So start out slow. If you're really scared of damaging your paint, try the machine out on a friend's old car that wouldn't mind. (they should be thanking you, actually). Or, go get a painted body panel thats in good shape at the junkyard. Or, just go at it on your own car and remember to take it slow, one step at a time.



Good luck!
 
Actually, I would like to think i posess all of those above attributes! The issue arose with a new product i was not familiar with, and obviously tried to figure out with additional time on alternate details. Have I figured it out yet? Nope!
 
I'm gonna agree with Patrick here... the time I experienced it was on the 2007 Avalanche I corrected (my brothers) the swirls were bad enough to justify the most aggressive pad and compound I had... 3 passes on his front fender left me with no swirls but a good amount of trails.... not severe, but they were there... a subsequent pass with a white pad and mild polish took care of them.



So I'd say its possible, not likely, but possible. And even in the event the PC does cause some trails they won't be severe IMO
 
I have too on soft black paint that was heavy on the defects...that was on the first pass, but after the next two steps, they were gone and the paint was clear

Yeah I was going to test out on some spare pannels first. I plan on using low speeds anyways since there's some light swirls on my car.



What kind of pads should I be using for light swirls and no major correcting at all? I'll also be using the PC to apply a sealers and waxes with also. I've heard the ornage pads, but how agressive are they compared to the others out others? Which pads should I be using for each process? My car is a bright red if that has any determination in pad use.
 
I have left 'buffer trails' on a heavily oxidized white single stage paint with a XMT 4.. Not really holograms per se like the rotary... But you could see a few lines where the buffer traveled for sure. I was in a hurry and just trying to knock the biggest portion of it off as quick as I could and wasn't breaking the polish completely down as I knew I was going to be following up with another step anyways.. It was a beater and I didn't really care since I own it.
 
I'm definately not going to be using a real abrasibe polish or a more agressive cutting pad.





Here's the kit I'm looking at: Porter Cable 7424 & Foam Pad Kit - Car Buffer



Would I want to use the orange pad for the polish, and then follow up with gray pads for sealant and waxing? What kind of polish should I be looking at that has very minimal abrasive, but yet still is able to correct minimal light swirls?
 
Could someone provide me some info on what pads I'll need to for what I intend to use the 7424 for? I plan on ordering one, but I need to know what I need first.

I would get the following: One or two orange light cutting pads, at least two or more white polishing, and then a finishing pad or two to apply LSP's (waxes and sealants).



You might not think you'll need an orange pad right now, but eventually you might so pick one or two up now. The polishing might be the pad that you use the most, so the more you have the less often you'll have to stop and clean them during a detail. Danase has a six pack (pick your own pads) offer that is pretty good:



Make Your Own 5" CCS Foam Pad Kit (6 pack)



Those are 5" pads which won't bog the PC down as much as a larger pad will. If you buy the 6 pack from Danase make sure you buy the correct size backing plate too.
 
Would those of you who have experienced holograms/buffer trails please respond with a step-by-step to show how it can be done with a D/A Buffer? I, and many others I'm sure, would be very interested to know what type of products induced that kind of marring with an orbital machine.
