gmck Posted April 21, 2011 Share Posted April 21, 2011 Hi Chris, I decided to do some more application experimentation, so first off I wanted to find out how easy it was to remove Opti-Coat. From the previous example, I wanted to remove it from the boot lid and decided to start over again. I had a high spot that I wasn’t even aware of on this boot lid, until a colleague pointed it out. Also your advice about Hyper Polish not needing an IPA wipe down swayed me, because I just don’t like IPA wipe downs. The paint on this BMW’s boot lid (which is on the skinny side anyway) mars very easily, unless you use a new MF, which was the original reason I decide on it, as a test for Opti-Coat. Because I’ve only been using Hyper Polish for about a week, I also wanted to do some more experimentation with HP and since I was removing the Opti-Coat, it seemed the obvious choice. I played around with both rotary and DA this time using LC Hydro Tech pads, Tangerine and Crimson on both machines. I’ve got some more questions about Hyper Polish, but I’ll leave them for later, once I get past the Opti-Coat queries, but I will say this, Hyper Polish is really good - I reckon I could substitute HP for 85RD if it keeps working the way it was today. As expected, it easily removed the previous application of Opti-Coat. The first time I applied Opti-Coat to this boot lid was a bright sunny day, so I was really surprised to find that I had missed a high spot. To-day was a really dreary dull day, so I think, I now agree with Corey (CEEDOG) in his review on AG that you really need different types of lighting to ensure that you don’t leave high spots. For those, who haven’t used Opti-Coat, discovering high spots after Opti-Coat has cured means that you have screwed up and have to start over. Another tip that first time users may find useful, especially if you are only testing on a single panel, is to make sure that when you first apply the pad to the surface that you start in the middle of the panel not the edge of a panel, especially if that edge abuts a panel you don’t want to apply Opti-Coat to. If only applying to a panel like a boot lid or a bonnet, it is probably also a good idea to prop the panel open, so that you don’t accidently apply Opti-Coat to the adjacent panels. For those reading that are familiar with Opti-Seal, you will find that Opti-Coat is somewhat more viscous as compared to Opti-Seal. My high spot in the original application was at the point I first placed the applicator and obviously I didn’t spread the product sufficiently enough and so created the high spot, which I then later missed because I wasn’t diligent enough when checking with the lighting I was using. Today I introduced a hand held Halogen to the mix and it even still initially missed a high spot, therefore I can’t stress enough the need to check from all angles using different lighting. I don’t want to make out that applying Opti-Coat is rocket science but you do only have a finite window to operate within. My main question relates to applying a secondary coat. I’d read somewhere that a second coat can be applied, but you need to do it fairly quickly. I couldn’t find where I’d read it, so I assumed that it could only be done just after the first coat starts to flash. Anyway that is what I did, so now I’m just asking for confirmation that I did apply the second coat at the correct time. The result after overnight curing looked good, so I went ahead and topped it with Opti-Seal followed by OCW. Last night I watched the Optimum video from DevFest and the first reaction I had when I saw the guy demonstrating the application of Opti-Coat was that he was applying too much product to the pad. It was reassuring when he told the class that he used way too much product. From my testing I would suggest that you start with a thin X on the pad and then you only need a couple of drops each time as you proceed to the next part of the panel. I certainly would use the blue tip to limit the flow, which is contrary to another post here. NOTE – I’ve just read Dr. G’s answer in the other thread, where he suggests high spots can be removed with Opti-Seal, so maybe what I thought was a screw up it is not such a screw up.
