SEM Trim Black on a camper shell

I picked up a ARE DCU and am going with a satin finish over the existing white.
I use SEM Trim Black often on smaller parts and really like the finish plus the stuff really holds up over time but have never used it on a large piece. Has any one used it on a large project?
Any suggestions on a good satin black paint? I’m also considering Raptor liner but don’t want a heavy texture. Can the thickness of the texture be controlled when using the Raptor spray gun?

 

I've used it on a majority of my former Delorean's body tub but that wasn't nearly as much exposed surface as a topper.

 

Yeah, using it on a large exposed surface had me concerned, after a little more research today I think I’m going to use the SEM Hot Rod Black.
