Very interesting thread!!
I applied Opti-Coat 2.0 to my personal car nearly 2 years ago. Reason for application was two fold.
1. So that I could concentrate on customer's cars instead of having to budget time to keep my own car waxed or sealed.
2. So I could torture the living crap out of the Opti-Coat 2.0 application on my own car, in order to see for myself whether an application of it would be something I could confidently offer my customers, or if it would just be another hollow marketing hype type of product that would be more of a liability than an asset for my customers and my detailing business.
I have regularly sprayed a liberal coating of a concentrated alkaline all purpose cleaner onto my car and allowed it to fully dry in direct sunlight, then I re-wet the car and wash it with a wash brush and car wash concentrate to remove any road film that the APC may not have emulsified. For days after washing the car like this, people often times comment on my freshly waxed car. They can't believe it when I tell them that I haven't polished or waxed it in nearly 2 years.
My prep for this particular application was to polish with M-205 followed by PO85RD both via rotary, wash with alkaline degreaser then wipedown with a cheap Glass cleaner (Basically RO water, vinegar and alcohol) and apply Opti-Coat 2.0 very sparingly followed by a very light wiping with a MF towel to smooth out any wet spots from changing directions with the supplied foam applicator.
I believe that if the vehicle is prepped properly, OC or OG should surpass the expectations of any car owner.
I offer OC or OG not as a permanent coating but rather a 2 year coating, informing the customer that the manufacturer calls it a permanent coating but my torture testing is only 2 years into the test.
Just my unsolicited 2 cents. TD
