smearing or actual holograms ?

Have some of you using 3M's MG 5937 noticed what first appeared to be holograms, but turned out to be just oily residues ? I finished polishing my metallic black car, using the above + Meg's finishing pad, which is very soft ( iused the rotary buffer at 1400 rpm), and when I was done I took in the sun and noticed those holograms :scared I applied Meg's #20 on a fender where there wsa some of those light holograms and after wiping #20 off holograms were gone. I had the same results using Meg's final inspection.



Before applying the sealant and using final inspection, those holograms appeared as ever so fine and tight patterned scratches, only in the sun of course.



Has this happened to you ?:nixweiss
 
I don't have any experience using that product with a rotary but I'm kind of thinking that you didn't allow it to break down completely or that you were maybe using too much product. You may want to PM Accumulator about this or at least bring this thread to his attention because he loves using this product with both the rotary and pc.
 
Heh heh, we already discussed this a bit...glad to hear it was smearing residue and not real holograms. I dunno why Chip Douglas was getting this problem...he was working the 05937 so much that he worried he was buffing it (too) dry :confused:



But then, now that I think about it, I'm always spraying FI/#34 on panels (or at least fogging them with my breath) after I buff them so maybe that removes such stuff from the equation when I use 05937. And I always do Cyclo work after using the rotary, which might also have something to do with it.
 
I vote follow with a pc and work the product in thoroughly and carefully overlapping 50% each pass in a number of directions.
 
Black Regal has a point!



I have seen the halogram effect before. I have seen it happen when you use too much product. Then there is just too much oil on the car.



When you went back over it with the next product, it solved the situation by spreading it out evenly and taking the excess off.
 
I've solved the problem, and here's what was wrong : I was using the wrong part of the pad--the part that cause swirls to be introduced. That is the part I used is the outer 1/3 of the pad, therefore the pad has to be slighty tilted. However the part that makes contact although it's 1/3 of the pad'S surface still is FLAT on the paint. I was told that by a very experienced detailler. I tried it and holograms were gone, totally gone. Prior to trying it I used the same Meg's finishing pad with Meg's 82, but still holograms, then went back to 5937 from 3M etc....all in all I've solved the problem, and I know for sure how I did :-).



I'm now free, and wont have to rely on a pc to finish the job of the rotary.
 
Dennis H,



after each pass, I washed the area up with car wash, rinsed and brought it in direct sunlight--trust me i did it the right way. I'm a perfectionist :-). Untill I did what I did described in my previous post, I'd get holograms.
 
I can even add that last year when I did my car, I did it using 3M's PI III MG 5937 with 3M'S convoluted polishing pad, and didn't get holograms at all, and then this year wit the same product and the same pad I got holograms. The only difference was that last year without actually knowing it, I was using only outer 1/3 section of the pad all along :-). I'm sold on this, really....what a relief to have found how to produce a good job without having to resort to the PC.
