Don't know the brand, but, I've seen plenty of outside ("Patio") furniture with texture paint on it, seen some that was bent and beat up (stumbling drunks-like), and haven't seen any chips. I felt it up and, seems pretty strong ... had the same idea myself a few times ...
I put Duplicolor Bed Armor (not the truck bed liner) on the outside of my CJ7. I will post a picture tomorrow. The body is from a YJ and the many layers of paint were in rough shape. I didn't want to strip the body and I didn't want to ruin a paint job by going through the woods, so I put bed liner on it. I saw a truck with it and it didn't look bad , so I tried it. I have also seen Durabak on someone's truck.
U-Pol Gravitex is a textured anti-stone chip paint. It goes on before your base coat. You can vary the texture by altering the PSI of the gun or distance from the panel. It forms a very hard chip-resistant coating with a heavy orange-peel texture. I used it on the underneath of my tub, but I wouldn't coat the outside of the body with it, I think it would look kind of silly.
I have just recently done a few projects with the Rutoleum Hammered paint. Bumpers, roll cage etc. Others have done more than I have. Search my posts on it to see my results & those of others. I believe it can be sprayed as well as brush & roll on. Pretty cheap too..... $12 bucks a quart at Wally World.
1982 CJ-7....not perfect but still alot of fun!
