Bedliner Over New Paint

[bridgeguy]

I have been told that bedliner type products (currently I am leaning toward Durabak as they havethe "traditional" texture as well as a smooth product that may work for the body (assuming I can get it as a totally flat non-glossy finish)) can be be placed over new paint or sealers. Does anyone have any experience/ information about something like that?

Additionally, I am looking for a totally non-gloss finish so if anyone has suggestions I am open to options for a final finish on the exterior.
