rotary buffer holograms

Hi,



I'm using a rotary buffer with Meg's finishing pad + #82, and I get holograms, are they created by applying too much pressure on the pad, or too little product, or moving the buffer too slowly ?



Let me know...





Thanks in advance
 
:D that's cause I insist on learning the proper method with a rotary, but I know you're quite right Dennis.



Aside from some holograms, I'm doing fine, which is excellent.



Take care
 
Well in that case try less pressure then change directions with even less pressure and so on but don't forget to overlap by at least 50% and keep the pad pretty flat.
 
I'm using Meg's finishing pad 6.5 '' with Meg's #82 swirl free polish, but I used a fair amount of pressure, which I had a hunch could be at the root of the problem.





Thanks Dennis for your input.
 
use moderate pressure for the first couple of passes and then lighten up to work the product in. Move the rotary at a smooth pace over lapping each stroke by 50%. Try not to go too slow over the same areas.
 
I don't use any pressure with the rotary but I'm only a rookie with the buffer. I keep the pad dead flat, many people angle it more and you wear out one section of the pad quicker than the rest due to heat build up. Also what RPM did you run it on?



Bet I'll learn a good lesson from this thread
 
Try to keep the pad as cleen as possible, dont buff the SMR until dry and using a bit of lubrication in the form of a spritz of Final inspection on the panel helps.



Sometimes however the paint can be too soft and using an orbital can be quicker and produce a better finish inregards to hollograms

I'm no rotary user, but from what I've read in other threads, hollograms are not an uncommon thing when using a rotary, even in the most experienced of hands. It's just a case of going over the affected area with a PC and a light polish to completely remove them. No big deal IMO. Is that right? Or have I read wrong information?
 
I think your right pugoman. To use the rotarty for the first few times and not get holograms in nearly impossible. It takes lots of practice. Even experts get them, but use the pc afterwards and they come out pretty easy. For me the 6.5 pads are a little small for the rotarty, i like the 7.5. Use medium pressure on the first couple of passes then lighten. Always move in the direction of the car, for vertical panels go up and down, on the side of the car work back and forth. Before you begin, step back look at the panel and plan out your attack, have your motion setup before you begin and take your time and move slowly.
 
Yeah, *anybody* can get holograms with a rotary, there are just *so* many variables that can factor in on each job. And generally, a PC/Cyclo follow-up is the best/easiest/safest way to deal with them.



But you could also try different products. I've never had holograms with 3M P-III MG (pn 05937) or with 1Z PP/MP. Some products are a *lot* easier to work with than others (including, IMO, some of the regular favorites :o) and I don't see any reason to stick with products that seem problematic *for you*.
