Hi, I am trying to sort out what I can use over Dupli color Self etching primer. had body panels sandblasted ( rusty old race car) and the blaster put Dupli color self etching primer right away to prevent rusting. I need to now put a filler primer over it as there are more than a few pits in steel. I was hoping to use a roller to apply the primer on the panels as I live in a residential neighborhood and homes are very close. Not set up for spraying it on with the modern requirements for respirators. Called Dupli color tech line today. They were not very helpful with information or what I could use over the self etch primer. I asked if it is Enamel or Lacquer based. He said neither. He said to use their Scratch and fill primer FP 101 which is Lacquer based. So what primer could I use with a roller (know alot of sanding involved) over their product. Going to have someone paint car when I get the body in better shape. The car will be used so not going to be a trailer queen. Thanks for any guidance on this.
