Upol Raptor and SEM Rock-it liner

This won't be long becaUse I hate typing on my phone. But I have been using raptor liner for a few years now. I've done about a dozen trucks and about 16 jeeps including my own. The stuff is great. Easy to control. I've been told by everyone including resellers that SEM rock-it liner is the exact same stuff. I did a jeep today using rock-it. After I mixed the catalyst into the bottles and started shaking it, I noticed right away that it felt like water and not like syrup like raptor. I actually went back to the directions to make sure it was the correct ounces that I added. It was.
I started with the tailgate first. A nice flat panel to test on. The second this stuff came out I didn't like it. It was like shooting a super soaker full of black water. The material acted like water, splattering everywhere. The raptor texture is like a bunch of tiny globs built on top of each other. This stuff is like craters on the moon. Opposite. I can do a tj tub in three coats with 3 bottles. I barely had enough using 4 bottles of SEM. Because of the splatter it was extremely hard to get a uniform coating like I have been getting with raptor. It's just god awful. I've been doing Berliners for years. And I've seen some of the nasty uneven garbage jobs in people's jeeps that the owner says it looks "great" and doesn't have a problem with. So before you chime in and say how awesome this product is mind you I actually have something to compare it to. This review is for those that want to know the difference between the two.

Hope this helps.

Since you have some years of experience and you may spray often, consider investing in a Graco E-10 along with some high pressure polyurea so that you can install some significantly stronger, no solvents, and much nicer looking bedliners.

if your going to spend the money on a reactor it will also spray rhino. we used to use poly at work and just recently switched to rhino. (were not using it for automotive use but for mfg of truck and buss lifts.)

If you're spraying Rhino Tuff Grip (most common Rhino product), it's a polyurethane and does not have near the tear or tensile strength of most polyureas. However, polyurethane is cheap, but you get what you pay for.
