Surface rust prep before sound deadning

I went the route of comfort:
- Firewall to bare metal
- Rustoleum primer
- Herculiner
- Noico 80 mil car Sound deadening mat, Butyl Automotive Sound Deadener
- Noico RED 315 mil (8mm)

Noico was by far the the most cost effective and had great reviews both on this site and amazon. I've taped the seams since and did a little more clean up but don't have pictures yet. I didn't buy the roller and had no problems installing the Noico deadening mat with a scrap piece of wood that I took the edges off of.
