Surface comes out streaky and oily

[Giz]

Not humid where Iam and Im having the same problems. Im wondering when I read Tims review on the M21, he never mentioned this issue.

IIRC he didn't have the seperation issue.

I'm going to keep my fingers crossed. While my #21 does separate when left alone, it mixes just fine and stays that way for days before it separates again. I have applied it in direct sun on a black car, in practical darkness(high humidity) on a black car, in the early hours of the day(in shade), middle of the day in shade on dark cars and had no streaking issues at all.

I have never had any issues with NXT paste. I have used it on my wife's black Stratus and it always looks great. I have never used #21 and probably never will as long as NXT and GC are around.

That seperation is normal. Mine stays seperated even after I shake it vigorously. Originally mine did not do that.

I hate to throw a wrench into everything, but I have the same problem on my black '67 Camaro and I don't use Meguiar's products. I use 3M Hand Glaze, followed by P21S Paint Cleanser and P21S pure Carnauba Paste Wax. All horizontal surfaces have the streaks. The only way I've found to counteract it is to keep turning my towel and following up with a MF Cloth. Lot's of elbow grease is needed to even out the finish. I've read that some people think that the streaks must be on verticle surfaces as well, but verticle surfaces become horizontal when you turn your head and I don't see them. I figured it had something to do with oxidation on the horizontal surfaces, but my paint is as clean as can be and it still shows up. Check out the picture, this car is clean!

Here's what I've received so far,


It is probably due to a combination of higher paint surface temp and surface residual left from improper washing/surface prep.

These products, (M21 & NXT liquid), contain a high levels of polymers which will fully cure within 24 hours. On hotter days with surface temp above 80 F, the polymers will set-up faster.

One can apply a second coat to smaller section using a DA or foam hand applicator pad, followed by wiping off using a microfiber towel. Not observing this problem on vertical surfaces leads me to think there is a surface prep problem.

Overall, I would suggest applying to smaller sections at a time, using a dual action polisher if possible, allowing the product to work its way into the paint with several passes, with an immediate microfiber wipe-off.

Hi:

Mike, thanks for the information and assistance.

It is probably due to a combination of higher paint surface temp and surface residual left from improper washing/surface prep.

I will have to think about this.

Not sure how you could get the surface prep. any better.

I always work in the shade and place my hand of the surface to make sure it is not to hot. Temps here in VA have been in the upper 70's to low 80's.

My 21 is very lumpy. No clear liquid, but a lot of lumps. I have a creamy solution with lumps of a soft substance floating in it.

Shaking the bottle does not cause the lumps to disappear.

What should the consistency of the product be like?

Thanks

This sounds like the product is bad and this could be why you're having problems, call Customer Care at 1-800-347-5700 and cite this thread and they should take care of this issue.

I'm sorry but I cannot disagree more with surface prep being the problem...

When we people such as Octane who have experinced problems, that kind of eliminates surface prep as a problem.

Also, if I am claying, then using 80 via PC at speed 5 until it is broken down and being wiped by a brand new microfiber, what could possibly be wrong with my prep? It seems that the surface prep reasoning takes the blame off of Meguiars and places it on the user. And in this case, with the wide varitey of complaints in this thread by different users of all different skill levels, I think the problem is with the product.

Well the information I passed on was a general statement, I don't think surface prep is the underlying problem for most people, it is a problem with waxes in general for a lot of people because they don't hang out on discussion forums and they don't have the skills most of the people in this thread posses.

Well I've sent the link to this thread to Mike Pennington and also to Jason Rose, so I can assure you they will read your feedback.

Monk,
I would agree with you, only times I have had issues with streaking is when it's hot and muggy outside on dark vehicles. Both 21 and NXT do it for me, but the common thread is the humidity.

I guess the simple thing to do is tape off a hood and do NXT on one side and whatever else you please on the other, and see what happens.
Also FWIW, I have not had this on my own black car, just the dark blue Accord. I have no idea what that means, but when I do the Accord again (a friend's daughter's car) I will experiment with taping the hood. I will mention again though, that the first time, perhaps I had not perfectly removed all of the 80, but the second time, it was just a wash and wax.

But as many cars as Mike has done, if it hasn't happened to him, it must be a user problem.
