[00:00:12] Hi, guys. My name is Richard Giles, Sherwin-Williams Aerospace Technical Service and training manager. I'm here at our training facility in Andover, Kansas. In this video clip we're going to be talking about a smart pair of our CMO 850 line and base coat clearcoat systems. This particular smart repair would be in paint process. It's very common and typical when a base coat is applied that repairs are needed. It could be from debris, any surface contamination, misalignment of delivery. So on the panel behind, we're going to wash it down with a product called CMO 110158. This is a prepaint wipe. This was developed for base coats and it's very good. It will not pick the edge. It will not soften the base coat, but it will take any tape gum and finger marks. Traces of contamination. We're going to prepare the surface, re wash with the prepaying wipe, and then from the application point of view, this is operator preference. You can use it either small smart gun or a full size turned down to suit the real estate of repair. But that, of course, would be operator preference.

So as the panel's prepared and cleaned? We're going to be mixing the 850. This is a three component material. It's a very simple one step procedure, its mix per product data sheet 4 base, 1 hardware and 3 parts of activated solvents. This base has been shaken by the way we machines shake every base but safety. We just give it everything a quick stir to make sure there's no settlement.

There's various ways of mixing, obviously, to a any given ratio because of the small volume needed and the smart repair itself. We use a small PPS, very convenient and very accurate. With these materials, all they require is a good stir. You have to be homogeneous and ready to go. So we'll clip it to one of the two guns on display here and show you the process.
[00:04:03] What we're doing today on the 850 solid color base coat repair is applying the color back over the repaired area up to full opacity. There is no special fade out or blend technique. It's a simple one step process and once cleared, will become invisible to the coat itself.
[00:04:32] So once the repair is complete, you can clearly see that we can see where the repair is. The oversight is very soft on the edges. What you'll find is once this is clear coated, it will become invisible to the overall scheme.
[00:04:45] Now that all of the repairs are clear coated, you can see that the color transition profile and the repair itself is totally invisible to the eye at all light conditions in all angles. The definition of a repair is where is it? If we can achieve an invisible aesthetic repair, that isn't noticeable to the inspector or customer and all light conditions we considered successful.
