I used the bedliner stuff because of the texture, so I am a bit biased. No clear coat on it at all and after 4 coats or so the level of texture actually seems a bit deeper. I'd just do a flat black if you don't want the rough look.
Is yours holding up well? I let mine sit for a while then decided to start over. I just peeled it right off no problem at all. Worried that it's not grabbing adaquaately. Maybe it needs to set overnight. Oh, and has yours faded at all?
