Mothers CMX vs Sonax Polymer Net Shield long term durability test

I tried the 303 treatment on my blades not too long ago. Except TBO I’m not sure if my blades are rubber or this new silicone. They feel a bit firmer than what I’m what I’m used to wiper blades feeling like. Who knows... It almost never rains out here anyways. Lol
 
So it may rain tomorrow and I wanted to see how my windshield would do. I took a spray bottle filled with tap water and sprayed the driver side liberally and the passenger side lightly.

I went for a drive. The drivers side with heavier water shed at approximately 35 to 40 mph. You can see the passenger side. Surprising!

I purchased some Griots glass sealant, but will not wait to apply it. Until I see if CMX does well in the rain tomorrow! I was scared but now I'm exciting hoping it does well.

Keep in mind car has NOT been washed since application. I have used my wipers twice with washer fluid to remove salt crud.

Rained a lot and very windy. Both sides of paint seemed to still have tight beading!

CMX was a success on windshield. Water flys off starting at approximately 40MPH! No issues with wipers either. I'm loving this stuff for the $20 price tag.

See attached photo for water behavior when parked or below 40MPH. View attachment 66061View attachment 66062
 
You will notice the top of rear bumper, by trunk opening is only place where beading is impacted. Appears to be uneven on both sides. Also this is the dirtiest part. I will wash with N914 at some point and see if it restores beading. View attachment 66076

Took car to my usual touchless car wash, one of the ones that's newer and in better condition.

Due to salt and grime I needed the undercarriage spray. Unfortunately it includes some Blue Corral foam option, NO Rainx or Armorall wax option was chosen.

Both sides seemed to bead very well after the wash in the spotless rinse.

Car came out about 98 percent clean. Bright white again and would suffice for most non autogeeks.

Of interest, I applied Griots glass sealant to just the rear windshield this past weekend. I just used N914 at panel prep dilution, sprayed and wiped rear windshield twice. Can't confirm it removed the CMX or PNS, but then I applied the Griots glass sealant per directions. Easy to apply. It appeared during the wash to shed water way faster than the front windshield. I may try to do half the front windshiled with the Griots and half with CMX.

I just cant polish and dont want to polish my brand new windshield. I'll do the panel wipe and IPA and then apply.

Attached is a pic of rear windshield with Griots rain beading.

The sunroof, passenger side CMX, drivers side PNS.

I'll update when I do a rinseless wash how the beading is.

In other news I picked up some Meguairs HCW, no clue why haha. I'll test that and CMX side by side on a black Ford or Lexus hopefully that are parked outside 24/7.

So as an update, after the touchless wash saw this on CMX side. May have nothing to do with the CMX. Seems like needs a good Iron remover. Possible this was there before or picked up while driving. Keep in mind with the city driving, there is alot of salt, grime, new construction, road construction and demolition I encounter on everyday drive. My last car was "accidentally" sprayed with wet cement splatter.

Rained today and both still beaded well and shed water. CMX on windshield did pretty good still too.

I'll try to wash one panel and perhaps spray with colored water to see if any difference. If anyone is interested.

Well I looked stupid taking the photos so far in this set. Standing in pouring rain lol. Last time I did this, someone asked if someone hit my parked car .

Had a torrential downpour, was parked in it, drove about 5 miles in it today. Parked again in it to capture more water behavior. Started coming down insanely, so I ran back from the garage to drive out and park in the rain hahaha.

So, interestingly to my eye, the PNS seems to have tighter beading now and perhaps keeps the panel dryer? Almost as if it shed water better and has different beading angle? No clue.

Remember now, last wash I went through was a touchless. Due to my pulled back and other issues I havent been able to do a rinseless wash. I'm assuming if the touchless left anything behind it is gone by now. If it isn't, the PNS and CMX side definitely have a discernible difference. Especially on the hood and trunk. The vertical panels still seem to bead tightly.

Surprisingly CMX is doing VERY well on windshield and still hasnt been removed from the touchless wash, wiper use and rain 2 days in a row.

When I can, I will do a rinseless wash on the hood and trunk with N914. Spray some colored water to see water behavior. That way we can observe and determine if CMX beading has indeed deteriorated. Just in case beading has been impacted by residue from touchless wash or traffic film/contaminants on the panels. Then make my final determination.

I will say I was a little surprised today based on the results.

Ask away any questions you may have!

Some side by side photos, left side PNS, right side CMX

Windshield with beads is slow rain, the cleared windshield is water running off during heavy rain.













 
I'm kind of surprised by the performance difference and OCD. I'm going to go do a N914 waterless wash on hood and trunk lid right now and report back.

Typed a long post and the app just lost it! So I will keep it short and sweet.
Ok, a bit surprised and disappointed by CMX performance I decided to wash with N914.

Just in case beading was being concealed by dirt/grime/touchless car wash. Which still to be is a bit disappointing. I still wanted to rule out CMX started to fail at barely the 1 month mark.

Process
Washed with N914 at waterless dilution. Sprayed panel heavily, then wiped and dried.

Sprayed with blue Crayola bath tablet mixed in water. Ingredients are
Sodium carbonate, sodium bicarbonate, citric acid, lactose, polyethelene glycol, mineral oil, blue#1 yellow #5 red #33

Then rinsed off. CMX struggled to shed the color and PNS didnt. CMX beads are irregular shaped and allows water to pool on a panel. The PNS just repels the water! Insane tight beads. See photos.


















 
CMX side vs PNS. PNS is the tighter beads.

Dont even feel like labeling because it's so obvious
