There is the videos on my you tube page of lots of testing I did pm me if you want the page address I will be re running them all as lot of new ones out new version of CQUK UNCR impressed on bmw before I sold it you have the gyeon ones ADS etc etc
I start a new job in couple of weeks working for a sports car hire firm and I will be restarting my own business up again now my mums cancer has halted a long side it doing New car protections only as well I love using coatings and i used to do so many new car protections I can fit these in round my my other job so will mean a lot more chance to see how these coatings do on the daily sports cars that will be hired.
As far as Opti-coat goes I still believe if applied right its one of the best.
This post is perfect in my eyes protection of car with OC then coated with BSD perfect upright beads and bsd helping to stop any water etching problems.

Its strange I have a thing about size shape and height of beading even from a wax as well if they are not even in shape size and height it puts me off.
I think some people think that these coatings are full prof and don't need any after care they do.
its like the talk of 9h I don't think a lot really understand the context of this
This was a interesting post maybe help others
There is a massive misconception with the hardness rating of products on the market and even more so in how this rating is represented in the market. There is far too much market focus on the said hardness rating of a product and not enough focus on what real world attributes these products really offer.
People are confusing the MOHS scale of hardness with a pencil hardness test.
Pencil Hardness Test
Method to measure coating hardness based on the scratching of the film with pencil leads of known hardness. The result is reported as the hardest lead which will not scratch or cut through the film to the substrate.
The Mohs scale of mineral hardness is based on the ability of one natural sample of matter to scratch another mineral. The samples of matter used by Mohs are all different minerals. Minerals are pure substances found in nature. Rocks are made up of one or more minerals. As the hardest known naturally occurring substance when the scale was designed, diamonds are at the top of the scale. The hardness of a material is measured against the scale by finding the hardest material that the given material can scratch, and/or the softest material that can scratch the given material. For example, if some material is scratched by apatite (5 on the MOHS scale) but not by fluorite (4 on the MOHS scale), its hardness on the Mohs scale would fall between 4 and 5
A 9H pencil rated product does not equate to a 9H on the MOHS scale.
On the Mohs scale, graphite (a principal constituent of pencil "lead") has a hardness of 1.5; a fingernail, 2.2-2.5; a copper penny, 3.2-3.5; a pocketknife 5.1; a knife blade, 5.5; window glass plate, 5.5; and a steel nail, 5.5. A streak plate (unglazed porcelain) has a hardness of 7.0. Using these ordinary materials of known hardness can be a simple way to approximate the position of a mineral on the scale.
So in other words I suggest people stop focusing on the said H rating of a product and make a more educated decision based more on chemical resistance, ability to self clean, ability to resist fall out / contaminants bird poo as well as the desired look you want to achieve and or water behaviour desired along with all and or any attributes the product offer.
Now what I have seen the more chemical resistant a product is the longer it lasts on a car
We all get fall out and tar on our car so we use stronger products to get them off its no good if these new type of products wont resist these.
And the word scratch resistance i don't think should be used mar resistance yes.
