Surface comes out streaky and oily

Where's the grease coming from? There is no grease in any Meguiar's wax. Grease is a lubricant used for things like wheel bearings.

In the case of the streaks you are talking about, this substance would likely be polymers.

I understand what you guys are talking about now... I had this happen to me once. It was very humid outside and I was detailing a Z4. I found #21 to be patchy, so I used some NXT Speed Detailer, and then use #16 on top of the #21, made an awesome finish. I took my time with the 16, making sure I had a nice uniform layer, I slowed down my arm speed greatly and used a 8006 pad, so it had very minor cutting power.

You can kinda see the blotchyness here...



SD and #16 later...




Try taking some QD/SD over the surface, then either another even coat of 21, or another wax.

I'm not sure where the "grease" is coming from or what it really is but if you look at the big reflection of the sun you can see yellowish sun rays reflecting off the surface of the paint, but then there is almost a perfectly vertical line (in comparsion to the screen, then line is actually running at a rigth angle to the vehicle) that is white in color with horizatial lines. It is the only ray that is a different color and is both longer and a different shape then the rest of the sun rays.

This is the "grease" that I am talking about. If you wipe a microfiber over it, the "grease" changes directions but doesn't come off.

Mike, it's definitely not grease...it "looks" greasy...I'm sure you're right about the polymers but it looks greasy...anyway, I'm going to QD it in the morning (been gone all day for Fathers Day ) before I go to work and we'll see if it looks any different...

After looking at the pictures more in-depth, I am beginning to think that maybe some sections of the applied 21 might not have fully dried. That could be the cause of the streaking. Thoughts anyone?

[TH0001]

I have let the 21 setup for over a hour before and still had streaking so I don't think that is the problem...

[SiriusRIMZ]

perhaps this is a result of #21 seperating, or sweating like its been known to do... Sometimes I've seen some light clear pockets of liquid in my #21...

wow, this is unreal, first time user of the 83, then 7, then 21 with the G100 this weekend, and I had those streaks as well. I am not sure of the humidity, but the product was fine, i just got it from ADS weeks ago. i have a dark green honda and it was pretty streaky in a few areas. i did take some QD with a clean MF and it seemed to help, i did this right after i removed the 21 and noticed the streaks, so it seems as though i didnt give the 24 hours to cure as recommended in this thread.
i did not let the 21 sit at all, is it supposed to sit on the car for a certain amount of time before removing? it seems some folks go both ways throughout this thread. i removed mine right away, essentially because i did not know any better--thoughts?

Update on my 21 experience

On Saturday I buffed out the hood of a black Inifiniti G35. I finished it off with M21. No streaks.

I made sure of two things.

1.) Thoroughly shook bottle so that when I squirted M21 out, it had the consistency of Heinz Ketchup and not a watery mess.

2.) The weather was around 80 degrees, low humidity. I applied it in the shade, wiped it off, then inspected in the sun and shade and no streaks.

Will continue to do more testing.

My neighbor has a brand new GTO that has clearcoated black metallic finish, I'll see if he'll let me use it for a test.

when you say "buffed out", what exactly did you do ?...and how long did you let the #21 set before taking it off ?

[OctaneGuy]

I evaluated a customers hood for paint damage by a rotary buffer in inexperienced hands.

To remove the buffer swirls, I used my rotary buffer with M80, made 2 passes. I followed that with M80 on a PC on speed 5, both using a yellow W-8006 pad.

Went from:


to



An intermediate shot. Swirled areas were protected by painters tape and MF towels during the test spot.


Hood isn't 100% swirl free because again, I went there to evaluate the customers finish and will do the whole car before a photoshoot next month. He was using a Japanese Synthetic Sealant type of product. I applied M21 right along side it, and there was no perceptible difference between the Japanese stuff he's using and M21, however this observation was limited to how slick it felt, and how it looked in the sun.

Yes, M21 should dry to a haze before removal. Normally 15 to 20 minutes but can be longer depending on the weather.

All of Meguiar's LSP (wax or sealant) need to dry before removal.

That should be a great test subject! Tell him I said #21 is the ultimate sealant for the GTO, and of course it is!

Make sure he got all the rail dust and other contaminants off the paint. The dealers are clueless, but it is better they not touch the paint. Someone told me that there could be adhesive left over from the material they cover the cars with during shipping. I need to get on the GTO forum and ask about that.

When I did my '04 in May with #21 I had no streaks. Weather was about the same as when I did the '06. There was less product separation back in May. When I had the streaks on the '06 I just left them there and let the paint cure for 24 hours. I used NXT Speed Detailer after it cured and the streaks came right off!

Hey all, new here to this forum but it looks great! I'm also starting a detailing business and have done quite a few cars and I have the same exact problem with NXT and Gold class as far as the streaking on dark paint. It's gotten to the point where I'm thinking about trying something else. I've always used Meguiars and love it but I can't be leaving streaks on customers cars. I've also applied it in high/low humidity, hot/cool temps and it does the same thing. I've skimmed thru this thread and is there a solution to this problem other than spending days on a detail job to avoid the streaks? Thanks.
