3 coating comparison

An update from last week. This pic is after hitting it with a hose. Hood hasn't been washed since coatings were applied. I believe the areas with no water are the tape lines.

Here it is after washing. I used D114 at 128:1. You can see the different action of water on different coatings is visible. Again, the McKee's and DG have similar sheeting, the center area with PA has strong beading.

Thanks for the review and the time to post.I would love to see Glosscoat used instead of duragloss.And the testing should be on washing after a month or so.Using a recommended carwash soap that a lot of members use to wash their vehicles will dictate over time the durability.It takes a lot of your time to give us results so I thank you once again.
 
Is the hood warm or cold? I have mckees on my car and it behaves totally different than what is shown here.It behaves like pa super hydrophobic and the beads will stay until either wiped off or driven.

I went with DG rather than Opt or something else more popular for just that reason - it's less popular. Not sure I'm following your point about about washing after a month. I washed it after 3+ weeks. I'll be using another rinseless once my D114 runs out. Need to find another one with no "gloss enhancers" or anything else that will mask the coating. Not sure what that is yet.

When it warms up a little I'll likely do a similar test on my LR3 hood. I can get 4, maybe 5 different products on that one. I'll be looking for inexpensive samples to buy or swapping product with some people here to give it try. Will be sure to include Opt in that one. I'd like to see how it looks relative to some of the others.

It was about 50 degrees when I took these pics. Interesting that your McKee's beads and mine doesn't. I didn't use McKee's prep polish and I didn't wait 24 hours before getting it wet. I assumed these weren't critical, but may have messed it up. May have to re-apply following instructions to the letter.
 
Very interesting to try mckee 37, it's sitting here for my next full correction and very curious to see how it looks/performs.
Thanks for the post.
 
Maybe something went wrong with the application of the coatings [not saying it's your fault] because it appears that both the Mckee's and DG panels are a complete failure from day 1 on that hood. I see absolutely no beading + that sheeting's just as bad.

No idea if they failed. But if so, why would it not be my fault? I'll re-apply the McKee's when I can and see how it looks. If it looks a lot different after application I'll re-apply the DG as well.

The reason I don't know if they failed is that I don't really know what to expect. For people who are getting beading off these coatings, I would ask what they're washing with or if they are topping. I'm very intentionally not using ONR, DG Rinseless, Uber, or anything else that will live a layer of something on the surface.

I've had the Mckee's coating (actually its predecessor DP) on several vehicles and had excellent beading many months no matter what I washed with, be it DG rinseless, Ultima waterless, CG citrus clear, etc. :dunno:

Reason I said that is because I know from personal experience how the littlest thing can effect the application of the Mckee's coating. Not too long ago I applied some to my car but didn't follow the directions and had poor results. But I did it over and followed the directions to the T and had it apply totally different compared to my 1st try.

Now all that's left is for me to check is how the water behavior is on it as I haven't gotten around to washing it yet. I'll do that now.

BTW, Uber better live up to its claims and not be leaving anything behind, because that's what I intend to use most of the time as a waterless wash to maintain my car clean.

There are so many variables to consider when testing these products.lets say the average car owner had applied Glosscoat.I would like to see the durability after normal washing with care within the 3 except for dg after 3 months.I use Glosscoat and serum on 95 percent of the time.I currently have gyeon on my personal car and after 4 months it's holding like the day I applied it.I don't use any Rw just a traditional washing when I have the time.sometimes I will run it through a touch less .mckees for the price is a awesome coating.so just to wrap this up the only way to determine durability is time and washing.
 
Give it 5 months with washing in between and then you can really tell the durability.I don't by 2 part coatings to much work.Thats why I chose Glosscoat.
 
Another update. Things look about the same. However... After using D114 I washed again with ONR on one side and DG Rinseless on the other. As expected, the beading and sheeting action changed dramatically. It's been suggested that my McKee's and DG coatings have failed for one reason or another (likely application error, imo). This is certainly possible. However, for those who have beading with McKee's rather than sheeting, I would ask what you're washing with. You may be seeing the beading from your wash product rather than the coating.

One more thought: first pic is of the hood as it sat outside. Under rain and dew all 3 sections bead. I only get sheeting when I flood it with a hose. If I allow the water to come down as drops it will bead every time. Not trying to be defensive about my application, just trying to ensure we're comparing apples to apples. I'll likely redo the McKee's and DG coatings and give them 24+ hour cure time just to be sure. Need to get my garage above 60F degrees before I try.

Before washing - rain beading.

After D114 - beading and sheeting as before.

Washed right side (pic) with ONR. About to do left with DG Rinseless. You can already see the difference.

Put the hose to it.

Some beading and sheeting is much faster, esp on the DG Rinseless side. Previously it was taking minutes for the water to slowly sheet off. With both DG and ONR, it's gone in seconds, almost as fast as the Polish Angel coating and spray (center) section. (For reference, McKee's coating on the right side of the pic, DG coating on the left.)

PS - not sure how to upload larger images. Do I need post to a web hosting site first rather than uploading directly?
 
Thanks for doing this test.

I don't apply coatings for a living, but I have coated several cars over the past 4 years.

The results do look atypical for coatings. Regardless of whether it was gtechniq, 22PLE , Wolfgang, Gyeon, PBL or Polish Angel, they have all sheeted more rapidly than what I'm seeing here - mean a few seconds at most. The worst performer in my experience was PBL. But all of them seemed to perform better than what your pictures suggest.

Did you do a complete prep?

Yes, you can read the details in my first post. I did cut the cure time short. They all got ~12 hours rather than 24 to cure, which could be part of the problem. If I can get the temps up I'll get the roof done with the same 3 coatings and maybe another 1 or 2. Would also work on getting the two outside sections of the hood polished and reapply coatings to the hood. The Polish Angel is behaving as expected and I'm not planning to redo it.
 
Decided to remove and replace this morning. Did one pass with Ultimate Compound and two with Ultimate Polish (orange and white pads). Then used the prep products with a blue pad. Got the garage up to 58 overnight and decided to give it a try. Clearly pushing the boundary on temp: neither coating flashed like you would expect, both felt noticeably thicker during application. I waited a few minutes to knock down high spots.

Not sure how this application is going to workr. Will give it at least a couple of days to cure. If this doesn't work well I'll have to wait a few weeks for it to warm up and try again. Used the CarPro applicator for both this time, and of course used a new suede MF sheet for each coating.

The redone coatings will have cured for 4 days in a heated garage before I take the car out tomorrow. Heated is relative - it never got above 58. No moisture expected until Saturday so coatings will have been dry for a week. I can't get a hose on them for a beading/sheeting example until it warms up. Likely Sunday.

I also sectioned off the roof and applied coatings there. I added Cquartz UK and Sonüs Ion to the mix. Did Cquartz UK because they sell samples and it's made to go on in cold weather. Used Ion because it's inexpensive and I like that it applies like more like a wax (similar to Polish Angel). Ion may be more of a sealant despite being called a coating.

Will give some details and pics on the roof application with next update when I get the car outside and can see how these look in the sunlight.

Something is definitely not right with the McKee. This is a single layer of McKee
