Meg's #7 swirling/hazing new paint

Last week, I had my front bumper repainted. This morning I was going to apply some #7 to it and tried a small 6"x6" spot with a dampened microfiber towel. When I backed away, I saw some serious swirling/hazing. I didn't know #7 was abrasive or did I do something wrong? This is worrying me since my paint is beautiful except for this one spot. Any help is appreciated. Thanks

Show Car Glaze is fine product, intended for this use.



Logic tells me that either your applicator or MF towel were contaminated...



#7 has no abrasive, to be sure.

I've been using show car glaze #7 for years with never an effect like this. It was a clean microfiber too. I'm going to try my polishing pal with a new pad to see what results I get before breaking out the PC to get out the hazing.
 
SnipeJDM- Sorry to hear about the marring, I too am :nixweiss



Must've been some kind of contamination or a coarse MF; as Jimmy Buffit said, the #7 is functionally nonabrasive on automotive paint.



Given your experience with the product, I'm assuming you didn't let it dry or otherwise do anything wrong, so the application/buffing media must be to blame.
 
The microfiber came from Pakshak so I know it was good and I didn't let it dry either. Now I'm wondering if washing the microfibers don't get out all the abrasives used when removing polish. Should I be using dedicated towels for each step?

Maybe that's it :nixweiss But I don't use dedicated towels exept for my glass and drying ones...this is a mystery!
 
I had my hood re-painted (paint + cc) on my car a few years ago by the local Honda dealer. He told me no anything for 45 days. Just wash with car shampoo. I said what about 3M IHG. He told me no. I obeyed him. Never had any problems.



Was the paint still too fresh when you applied the #7? What did the body shop tell you?
 
The body shop said no wax for 30 days, but my experience says 90 days. Most fresh paint jobs are compounded and glazed at the shop before it even leaves so I figured this wouldn't be a problem. It never has been in the past anyways. Either way it is still a mystery to me and I'll use only fresh foam pads in the future if I'm doing it by hand and see if it makes any difference.
 
One more question.



If you take that same damp MF and the #7 to a clean CD, will it leave the same scratches on the CD?
 
SnipeJDM- Yeah, you didn't do anything wrong. If the paint was dry enough for the car to be returned it was OK to use the #7 on it. Shops often abrasively polish (and even do wetsanding) on fresh paint before the customer even sees the vehicle, they just don't tell you about it ;)



Oh, and on the "how long to wait" thing (we really need a sticky on this topic), MirrorFinishMan recently contacted all the major autopaint manufacturers for the straight scoop: the *MINIMUM* time before waxing/sealing was 90 days and many recommended even longer. You're smart to wait as long as you do. Funny that shops don't give people the straight story :nixweiss
 
Thanks guys for the advice. I'm pretty familiar with paint and body as I took some weekend classes at a tech school when I was in high school and have done some painting/wetsanding/compounding myself on many occasions.



I figure 90 days in the FL heat will be enough to cure the paint hopefully.



Oh by the way, thanks for the suggestion of the CD test jsmc. I just busted this wide open. Tried some #7 on a CD with the same towel I used this morning and lo and behold scratches and marring. Broke out a megs foam applicator with #7 and no scratches no matter how much I buffed. As a control I then picked up a new and freshly washed miracle towel from autogeek and gave it a try. Guess what? Scratches again. Now I'm puzzled. Is it my water or something I wonder? It's city water, but it is very hard since I live on the beach. This requires further investigation.
 
thanks for the test...



Don't know if its your water but the theory still holds true. If the towel or polish induces scratches on a CD it MAY scratch your auto paint. If the towel or polish induces scratches on your auto paint it WILL scratch your CD. Again thanks for your time.
 
At least you've discovered the problem. Try putting some distilled white vinegar in the final rinse cycle when you wash your MFs.
 
I think I realized why my MF towels seem to be micromarring...



I've heard that scented laundry detergent leaves a residue in the towels... Now I gotta try and find one that doesnt!



My MF towels are Mountain Fresh, but I doubt that's what I want for the car's paint :nomore: :tribe:
