I've used the red herculiner on the exterior, just did this a few months ago. I went with it bc it was cheaper, easier for me to get and I had used the black herculiner with good results. I'll see if I can post pics this evening. I think the texture came put good and it dried hard. It's probably not going to be as hard as monstaliner or raptor but that's due to the rubber particles. I wouldn't say it's soft though
I have heard of concerns with fading but my Jeep is only driven on weekends and when it's not being drove it's in a garage, so I can't speak to that. It seems to me that you could use an armor all or mcguiars cleaner/Protestant to help against UV fading even though it already is supposed to have UV protection. It does catch dirt/dust but nothing that doesn't come off with a power washer.
Plus you never have to worry about a scratch or waxing, lol.
