I'm getting close to getting my bumpers painted. I have some pieces left over from chopping my bumper so I did some testing today. I scuffed it up with a sanding pad then used a primer/etcher. Then I used rustoleons bed paint. There paint seemed to have less texture to it. It turned out real nice and I had to work pretty hard to scratch it so I could test out repairing it. The repair is drying right now and looks pretty good so far.
