People,
Opti-Coat, if applied properly and allowed to cure properly, can be polished with a mild/finishing product and a finishing pad with little effect on the coating.
I have done this on numerous vehicles and it appears to have very little effect on the properties of the coating.
If the need to polish Opti-Coat comes about I recommend using the least aggressive method first. I will personally reach for a black LC finishing pad and something like FPII, 3M's UF or the new Optimum Finishing Polish (completely new) and first use my Flex DA to see how that works. If needed I will use a rotary.
If I must use something more aggressive then I will do the entire panel and re-apply Opti-Coat. While Opti-Coat will have a difficult time adhering and bonding to itself after it has cured I have found that it can be re-applied to an area that has been polished and then prepped properly. In my testing of this the Opti-Coat has not been completely removed but rather, for lack of a better word at the moment, "lightened" thus allowing for a "booster" of Opti-Coat to be applied.
I do not recommend doing a "patch" re-application of Opti-Coat as this may lead to odd streaks and an uneven finish. Do an entire panel and the results will be far better.
Lastly, Opti-Coat CAN be waxed over, even a sealant applied over it.....not really needed though and will most likely not be as effective.

If OptiCoat gets scratched by washing then it needs to be removed in order to deswirl the car. Removal kind of defeats the purpose of applying a coating that lasts for a couple years.

From what I understand, if Opticoat gets scratched then you can polish it like any other clearcoat.

Opti Coat is a clear coat. It is not a nano sealant. It is not scratch proof. The benefits are that it contains polymers that, when cured (dehydrated) have a hardness approaching 9H, it has truly unparalleled hydrophobic properties and is extremely resistant to contaminants. You gain some thickness and some UV protection for your existing paintwork thus prolonging it's life and if you need to polish, you will be removing swirls in the coating layer instead of the actual car finish. I'm not sure what kind of unrealistic expectations some of you have thinking it should be bulletproof and you can now wash with a scotch bright pad or something. It is verifiably harder than any currently used clear coat which give you a significant margin of error, but you should still take care practicing safe cleaning and not use it as an excuse to do shotty work or start using tunnel washes that see hundreds of cars per day using the same wash media.
Okay, I found the time to do a little testing of this idea. I had a few wipe down light swirls likely from a contaminated towel. So I got out the RED flat LC pad/pc/205.
after a few passes the slight swirls were gone, but the perky beads of the water were no longer perky they had flattened out. The coating is still there, the water is just slower to blow off or sheet off.
Conclusion(s)
1. 205 is much to abrasive even on a no bite pad than I originally thought
2. Opti coat is durable stuff!
3. I'm not sure I could get the slight swirls out with a less aggressive media. If the idea stands to remove marring is to "level" the surface below or at the level of the marring, then no matter what I use I have to follow that same line of thought, correct? If I used FFII I would still be removing the coating down to that level to remove the swirl.
4. The statement of a 9H on the mohs scale is hard to accept, that is much harder than quartz (7H).....diamonds are a 10H. IIRC I could use talc 1H and not scratch a 9H surface, I can scratch it with talc and little kinetic effort.
5. Don't plan on polishing without some measurable reduction in the properties.
6. The coating can be removed without too much effort using 105/300 and a cutting pad on a PC. I was much more worried I would have to break out the sanding disks!
After I've written all this I hope it provides you with some information, answers some questions.
HOWEVER, this test does not provide any quantitative measurement (#s) of findings, but rather on a subjective qualitative measurement (value based) of the viewer.
Cheers,
