Re: I'm completely baffled...

Does this happen exclusively with liquid waxes or pastes too?

Well, I pretty much use liquid waxes exclusively. I made an exception with the EZ paste wax. But I don't recall streaking with either of my Auto Magic liquid waxes, although it's been a while since I've used them.

Re: I'm completely baffled...

I have another thought on this, and I'm not 100% sure if I'm right or not, but here goes. In another thread, I mentioned that I had great success with Ultimate Compound on my hood, which I did. If I were to take a guess right now, I would say I achieved somewhere between 80-90% correction of the swirls and scratches in my hood. Whether I look at the hood in the sun or under bright lights, all I see are some faint lines left over. I think one more pass would have me covered. Keep in mind that I only did one pass by hand. Here's the thing - I'm now thinking I didn't underestimate UC at all. I had done some test spots with UC on my driver's side front quarter panel, my driver's side rear quarter panel, and on the trunk with little success. So why would I have success on the hood? I seriously wonder if the paint on my hood is perhaps softer than the paint on the rest of the car, and this maybe has something to do with the streaking. Why it would be softer, I don't know. Again, this is just a thought, and I don't even know if I'm right, but it does give me cause to wonder.

Maybe give Gold Class or NXT paste and if you can find any M16 a try?

I say M20 Polymer Sealant is worth giving a try first. You would be suprised just how often I will choose it over M21 2.0.

This was more to what I was getting at. I don't think there is anything wrong with what you are doing. You've detailed a lot of vehicles,so you know the procedure.
Why don't you ask 'Shyneman123'? He knows a good bit about this.

Re: I'm completely baffled...

Questions

1. Is the car clear coated ?
2. can you measure film thickness on the hood, roof and deck lid ?
3. Is there a insulator on the underside of the hood ?

can you send me a pic of the hood ,roof and deck lid the same distance away?

So far my guess would be the feeder oils in Meg's

I have had several GM vehicles in the past were the hoods paint fails first from sun and underside heat from the engine.
And the only satisfactory final result was to stop at polish due to the dead paint drawing the wax into it and streaking.

PS. your pm is full

1. Yes
2. No, I don't have a paint thickness gauge
3. Yes

Like I said, I think the paint on my hood is softer. I can't say for sure, but I think the clearcoat is fairly thick. Just a guess. There are no signs of any clearcoat failure. IMO, my paint looks better than the paint on some 2 and 3 year old cars I've seen. I will try to get some pics.

P.S. I cleaned my PM box up. I didn't realize it was full.

I do have some pics of my hood, roof, and trunk.
This is probably my best pic of the hood:

Re: I'm completely baffled...

OK, well I decided to go ahead and wash my car tonight, since it had been about a week or so since its last wash, and I thought since I was at it I would go ahead and do a little test with two waxes: M21 2.0 liquid wax, which does streak on my hood, and Auto Magic EZ paste wax, which doesn't streak on my hood. The fact that one is liquid and one is paste should not make a difference.

Whole car washed with Gold Class soap, 2BM, microfiber chenille mitt
Dried with the Absorber
Hood clayed with Clay Magic blue clay bar and Quik Detailer
One pass with UC by hand on hood

Time of test: 7:30-8:00 PM
Temperature: mid 70's
Humidity: around 60%


Right side
Waxed with Auto Magic EZ paste wax
Allowed to sit for exactly 15 minutes
Swipe test performed
Wax removed
Check for streaks

Left side
Waxed with M21 2.0 Synthetic Sealant
Allowed to sit for exactly 15 minutes
Swipe test performed
Wax removed
Check for streaks

To ascertain that the results were not skewed in any way, shape or form, each wax was applied with a brand new applicator pad (straight out of the pack) and removed with a brand new Supreme Shine microfiber towel. I used a separate applicator and microfiber for each wax.

After wash, clay, and UC


Auto Magic EZ paste wax


Nice, thin coat of wax


Swipe test after 15 minutes - clean swipe


Right side after EZ paste wax is removed


Streak-free!


M21 Synthetic Sealant


Nice thin coat of wax - swipe test performed after 15 minutes


You kind of have to look close in this pic because my lighting was not the best, but you can see a light brownish colored streak in the middle of the pic. I only got this streaking on the side with M21. All streaks were removed with #34 Final Inspection.


All done! Which side do you think looks better? They look about the same to me.


So, any thoughts as to why I might be getting streaking? Conditions were about optimal, there was nothing to blame on towels or applicators, so I'm stumped. Thoughts?

Re: I'm completely baffled...

You might want to let M21 2.0 sit a little longer, even it it passes the swipe test. You have to find the "sweet spot" so to speak. You do not want to remove M21 2.0 too early or let it sit too long.

Are you folding the Supreme Shine 4 ways when wiping the wax off?

The last time I used M21 2.0, I started on the driver's side front quarter panel, went around and did the whole car and did the hood last. Then I went back and removed the wax in the same order I put it on, starting with the driver's side front quarter panel, and removing the wax on the hood last. The wax on the hood sat for about 15-20 minutes, give or take a few minutes. I still got streaking. And yes, I fold my microfibers 4 ways when removing the wax. Wipe off with one side, buff with the other side. When one side gets "loaded up", I flip to a clean side. I have no problems this way - only when I get to the hood do I have issues.

Re: I'm completely baffled...

Hey Shane,

From the looks of your swipe test of the M21, it appears that it has not set up enough as there is a smear in the swipe. Allow the M21 to sit a little longer until the swipe test comes up clean, then remove. I have seen this before many times and it is usually caused by humidity or other factors that increase the general set up time too a much longer interval.

If you continue to struggle with it though, switch to M20 as I have used it for over 2 decades and I have to say it is still my most favorite Meguiar's product after all of these years.

But why am I only having this problem on the hood? Under the exact same conditions, setup time for M21 is about 15-20 minutes on the rest of the car. Then I can wipe it off and it's as clean as a whistle! I completely understand what you're saying, and I agree 100% with you, but why my hood? I just don't understand it.

Re: I'm completely baffled...

Hmmm, MAYBE because more light reflects off the hood to direct more light to your eyes than other panels? Just like I rarely see swirls on my cars side skirts, even though I know they are there.

Have you tried using Ultimate Wipe to remove the residue?

Re: I'm completely baffled...

Take a clean damp towel and fold it in a pad and wipe in even strokes from back of hood to front until you have done the entire hood. This should remove the streaking.

Let me know
