Thanks guys, I was able to pickup some PPG flattener so I'll give it a whirl. It's only being use in the trunk and passenger compartment so it's not real critical. I just thought it would be good to tone down the gloss as some areas are exposed and the surface prep was not done to a show car finish. I'm thinking the dull finish will help hide any inperfections and not make any future surface scatches as noticable.
