I think it's user error. Maybe not enough was applied or something. There are too many variables.
If you have used this product and you are getting fantastic sheeting, I am happy for you. I could understand how you might conclude that "user error" is the cause of it not sheeting fast. Please post your experience and videos to share with the community.
This product is very easy to apply. You spray the applicator with a mist or two. When you apply it to the paint, it wettens and darkens the paint where applied. As you make your passes, it eventually starts to dissapear.
I worked in small sections and applied it in back and forth and up and down fashion to ensure full coverage. You can see where there might still be too much product, because the paint would be a little darker. You may have to move your head around to get the right lighting. I even applied a second coat 24 hours later.
It is very similar to opti coat or opti seal in application, if you have ever used those products, but easier. Yes even easier than Opti Seal! You don't get the oily rainbow effect, high spots, when lifting the applicator off the paint. And I love using Opti Seal.
If you clay, polish the paint to strip old sealant or wax, use Squeaky Clean, follow the manufacture's directions, and are thorough with your coverage, I really don't see how anyone could screw this up.
It is raining out today. I will leave you with this video. DGNCC on passenger side, DGNCC topped with reload on the driver side.
