I sandblasted all the parts on my truck and have been very happy with the process. I just did my hood, no warping at all. It uncovered some weak rusty metal, but better to know about it before the expensive paint job! One problem I had is that I cleaned the metal with a grease and silicone remover which is good, but the lint-free rags I used left tiny lint on the metal. This must have been due to the "tooth" on the metal. It was a friggin nightmare. I sanded the entire thing with 80 grit and it seemed free of lint. Once I started spraying the epoxy, I could see that there was still a lot left. Oh, well, I will be block sanding the truck back down to metal anyway, just needed to keep the metal from rusting. Any ideas on remedies for this?
