Default Seam Seal Firewall

I'm in the process of seam sealing the firewall on my 67 GTO. How are you guys seam sealing the firewall to get clean straight edges? I masked it off but when I pull the tape off it wants to pull the sealer off the taped edges a little. I pulled the tape off as quickly as I could. But I think it is starting to skin over before I finish applying. I have tried 3M brushable and now I have some 3M urethane and Dynatron I want to try. Any suggestions?
