MF towels wont cause "holograms", just scratches if they are dirty or pick up dirt. Yes you should wash them before using.

I agree a white pad isnt meant for applying glaze. A black or blue pad is best. Also when applying glaze with a PC use a low speed, say like 2 should be fine. I have done this with sealant and a black pad before and never had an issue.

After applying the glaze, give it a little bit to start hazing over. Buff gently with a MF towel, then flip it over to a dry clean part and wipe it again. If it takes a lot of elbow grease to get it off, you probably applied too much. Do this to one panel at a time.

If you wish, after you put a coat of glaze on the whole car, you can do a wipedown with some QD.

Hope this helps.

 

Also, what glaze are you using?

 

3M Hand glaze

 

Poor quality micro fibers can cause scratches. Technically holograms are caused from machines especially rotaries when the polish is not worked in to the fullest extent.

 

I have never used 3M glaze before, but I have used Meguiars Glaze before. They are similiar if I remember correctly. Just use the aforementioned advice.
