Walt Posted August 25, 2014 Share Posted August 25, 2014 I have recently done a Sapphire Black BMW with the OptiCoat 2 and I am delighted with the results. I think it's a remarkable product. The paint was well corrected with the Optimum Polish II, which I also like very much. As carefully as I examined the corrected paint with florescent, halogen and LED lights before applying the OC2, I have since discovered a few defects (water spot etching) on the roof that I would like to correct with the OP II. The OC2 has been on the car about two weeks in fairly warm weather. I know from reading the forum that by etching the original OC2 with the OP II, a new coat of OC2 will adhere to any OC2 remaining on the surface after the new polishing is done. But I'd like to redo just the few spots and not the entire roof panel, which is quite large on this 750i. So there will be only three 1-2" diameter areas that I would polish. There will be a boundary where the "etched" areas from the new OP II corrections stop and the undisturbed (unpolished) original OC2 begins. Will there be a blending problem here? What does the OC2 do in areas where it does not adhere to unpolished OC2? How should this issue be handled? Many thanks, Walt Link to comment Share on other sites More sharing options...
