1. Are you guys confident regarding the safety of these coatings for the long term? Convince me that some years down the road the clear coat will not turn bad due to some unforeseen chemical reaction between the clear coat and topical coating.
2. What about the environmental contaminants such as metal and/or dirt specs that get imbedded into the finish? Clay and/or ironx is used to rid the surface of these things. Won't these long term coatings need to be cleaned annually of imbedded debris?
3. What are the "high spots" mentioned as possible during the application? Is this stuff that thick that it can have visible high spots?
4. Could a first time diyer really screw this application up? I'm thinking the DuraGloss might be much more user friendly to us newbies. But still, I am a bit leery to try it.
5. Can it be removed if needed? How?
Thanks, Mr. Critic for dangling this new product before me just when I was ready to do my biennial Zaino order.
1) From my review of the MSDS sheets for both Opti-Coat and CQuartz UK, I do not see anything that would be of concern.
2) It depends. These coatings will resist soils and contaminants from sticking, but they are far from perfect. An annual Iron-X and light clay de-contamination is probably a good idea.
I have found that contaminants will stick to Opti-Coat 2.0 if the car is not washed on a regular basis. Of course, the trouble here is that the definition of "regular basis" is going to vary wildly from person-to-person.
In fact, I'm dealing with a situation right now where 2.0 has stopped beading completely after the car wasn't washed for a few months -- but I'm sure that de-contaminating the car will fix the problem.
From what I've seen so far, CQuartz UK appears to be less prone to this issue. I do not have enough experience with Opti-Coat Pro to comment on whether it has the same issue as 2.0 -- but Opti-Coat Pro doesn't have a lot of the deficiencies than 2.0 has.
3) The high spot issue is a bit overblown, and is something that is more exclusive to Opti-Coat. If the surface is properly prepped and the coating is applied thinly and evenly, any high spots will be easily wiped off after the suggested wait time. However: 1) high spots can be difficult to spot on light colors, 2) if you apply the coating on the thick side, after 5 min, the residue may not have fully "flashed," so you may end up smearing some of the residue around.
I have found that UK is much easier to apply than Opti-Coat. The reason is because you can see where you've applied the product (unlike Opti-Coat, which mostly disappears), and the residue is removed like a traditional sealant.
Here is a video on how UK is applied:

4) Screw-up? Sure. Coating failure can be an issue if the surface is not completely free of oils and polish filler residues. Some coatings seem to be more sensitive to this than others. UK is definitely the easier one to apply than Opti-Coat. I do not know enough about the Duragloss one to comment, but I did read somewhere that it flashes and disappears quickly...
5) A light finishing polish will remove it -- something like M205. If you are using UK or Duragloss, you will need to do a light polish after 18-24 mo to remove the old coating and re-apply anyway.
