Today i painted the firewall on my street rod getting ready to put the body on the frame, everything went pretty good except i did get a few fairly large runs in it, i used a dupont b/c c/c, What would be the best way to get the runs out of it? I do have some 1500 and 2000 sanding paper i purchased thinking i might have this problem since this is my first go at painting. I would just like to get some feed back before i jump into it and screw up. Ron........
