Organsol is a type of paint that is textured to look original. It is flat black in nature. As far as different manufactures, just remember, you get what you pay for. The originals are nice if you are trying to keep it numbers matching, but they do not hold up over the years. The new ones are either fiberglass or abs plastic. Abs plastic over time will warp, like the original ones did. As far as the holes to be cut, they are cut on the inside frame part of the trunk lid, so that a bolt can be put through it into the new spoiler. I have added a pic so that you can see where the 4 holes are cut. If you buy an aftermarket trunk, they do not come with these holes in it, you need to cut them yourself, like I did.
