This was rolled on super early in the pot life of this batch and then left alone, so it's super smooth with almost no texture at all.
This is what it looked like when I rolled it onto a fiberglass thingy I made - I kept going back over it with the roller as it set up, so that raised it and gave it a bit more texture.
Pics don't really show it, though. It's almost flat on the sample card, and has enough texture on the fiberglass thing and my tonneau that you know it's bedliner, but not enough to add significant traction. I think if you kept rolling as it dried you'd get more texture, and they sell a rubber crumb additive if you want it chunky like a professional spray-in job.
