Surface comes out streaky and oily

I definitely think this is a factor, at least for me. #21 never streaked until it turned lumpy. Could storage in a M-9912 be a factor? I don't think it is as air tight as the original big bottle. I find #21 to be one of the easiest LSP sealants to use. One wipe is usually all it takes to remove the haze.

I think Meguiars should offer #21 in the traditional 16 oz. bottle. I think they'll sell plenty of it in that size!

Certainly there can be other factors too like heat and humidity, surface prep, or maybe applying too much. But if all those factors are addressed it's the product. Octane Guy had low humidity, he definitely has the right surface prep, and knows what he is doing being a pro detailer. So I think in his case it's the product.

Oddly enough heat and humidity did not affect MPPP. Now cold and humidity caused a problem where it took too long to dry.

Another interesting observation is that the NXT paste never streaks, even if I apply too much on a hot humid day!

My 21 was never lumpy...infact it was brand new out of the Meguiars bottle and I had streaking issues.......

I am doing a Vette tommorrow that is dark green for a car show on Sunday......I wish I had more confidence in what would be the outcome.

If you're getting a car ready for a show, use NXT Paste instead. No streaking issues and the look cannot be beat IMHO. You're not looking for durability now, although durability of NXT Paste is OK, just not like #21.

And get some NXT Speed Detailer to get any dust that may get on the car during the show.

This is why I think the seperation is an issue, at least with the NXT liquid vs 21...

My NXT rocked until it seperated, and now it streaks like crazy. I just used it to top 21 today on a wife of my friends. The 21 went on perfect (black Nissan) and off via PC. Then I topped with NTX liquid on half the hood to see what would happen. Dark spots every, but the 21 did great today. I applied the NXT very thin also....

Maybe there's different reasons to the streaking. One reason might be caused by the product separating. But as I've read through the thread, I've been thinking that another reason could be, that the 21/NXT dosn't cooperate well if there's a slight polish residue left on the paint from the previous step. I've noticed that one guy had problems used on top of DC2, another over #7, and several have had problems when used after #80, which is also very rich in polish content.

So just thinking out loud - maybe the polymers have trouble bonding properly if the paint is very rich in (too much) polishing oils left from the previous step, and when removing the LSP it starts to kind of smear around in the oils etc. left from the polish?

Someone who has the problem could try to do a side by side comparison, with both sides prepared the same, but one side wiped down with a solution of 50/50 alcohol/water, before the LSP is applied. Then we could find out if the smearing is actually caused by the product used before the LSP...

Then maybe the problem can be avoided by very thoroughly wiping the surface before applying the LSP. Also using Mike's "slow wiping technique" when removing the polish, might help the mikrofiber absorb excess polish left on the surface.

I'm going to wash my truck on Monday. It currently has 80 followed by 7 followed by two coats of 21 followed by 26 (which I'm sure is gone by now).

I will do your test, I will clean the truck, clay the hood, rebuff with 82 via 9006/PC, then wipe half the hood with down with alchol then report my findings on here.

ok...I think I have a picture of what we're all talking about...let me explain what I did today...it was about 78 degrees with 50% humidity...I got a shipment from ADS yesterday of #21 and #80...so this morning I:

* Washed with NXT Wash
* Clayed
* #80 with 8006 pad on PC removed with MF towel
* #21 with brand new 9006 pad on PC set at 4
* Removed # 21 after letting it set for 30 minutes with 7006 pad
with MF bonnet set at 4

The product itself was perfect in terms of consistency. It was only a small bottle that I bought but after shaking it for about a minute, it came out of the bottle as I expect it should, smooth.


This is what the hood looked like after claying and #80...this is inside my garage and it's reflection of the ceiling:


Here it is with #21 applied


Removed and pulled out in the sun....you can see what looks like smearing or darker "oiley" spots on the right side of the hood to the left of the clouds...



I'm going to do a second coat in the morning tomorrow to see if it makes a difference...and I only notice it in the hood and you had to be in the right light??...weird...otherwise #21 looks as thought it brought out more black in my car than ever!!!....we'll see what tomorrow brings

[RamAirV1]

Looks like you did everything right to me.

Maybe you should take a section and remove the #80 and just use #21 to see what happens.

It certainly doesn't look like you applied to much #21.

And the consistentcy looks very good on your #21. Mine isn't even close to that. Mine is all lumpy and seperated and no amount of shaking helps at all. Mine originally did look like yours though.

Paint looks great except for the streaks.

Yep, those are the dark streaks I have noticed...

Perfect example.....

Have you ever noticed a fine layer of grease on the surface, that causes the sun light to streak (looks like superfine swirls, only visible in "rays" coming off the sun) that changes directions when you wipe the surface, but you can't wipe it off?

I get one or the other, or sometimes both.

Try this...

I suggested this earlier, but maybe no one saw it: Try wiping down the car with 50/50 IPA alcohol/H2O after polishing and before the wax. This should help any remove any polish residue that your initial wipe-off doesn't get.

If your 21 is lumpy and seperated, I think it has gone bad, and in which case, Meguiars will probably get you a new one.

I don't get any streaking myself, but I think the above method will actually remove not just polish residue, but the polish itself which will defeat the purpose of polishing. A final wipe with a MF using slow passes should do the trick if there's any residue left.

[RCBuddha]

Yes, it will remove oils from the surface, but it will leave a squeeky clean surface to which you can apply an LSP to. I have NEVER seen a finish become worse by using the mixture to clean the surface.

However, I can see how if your using a glaze, your trying to fill-in marring, in which case the 50/50 solution may not be good to do.

I have but I just thought that it was because I hadn't let it dry long enough...I put a second coat on this morning and here's the results;

[TH0001]

It looks likes more streaking in the second picture, but I can't tell do the quality of the monitor I have at work. Is there more?

[TH0001]

In the top picture you can definatly see the grease coming off the sun (looks like a streak running up and down with the "swirls in it".
