I'm happy with my herculiner, I took my time sanding and prepping though (it took me something like 4-5 hours to prep with a palm sander, hand sanding, and cleaning multiple times)... I carry plastic boxes/drawers filled with detailing supplies, generators, and power washers all day long and there's not even a scratch in it. Here's some pics of mine:
After 1 pass of sanding:
After 2 thin coats (still wet):
After a total of 3 thin coats dried for 24 hours:
I ended up going and touching up a couple spots after it cured (like the run on's you can see on the back part...)
Close up of the texture:
my buddy has an s-10 and had his professionally sprayed in.... I guess it looked a little better aesthetically in my opinion. As far as durability I didn't see any difference though. I personally didn't see the point of spending $400+ when it can be done for about $100 and perform just the same.
