[Project_Gotham]

I got the car back from the media blaster, I had them blast the whole floor of the car, bottom and top, from trunk to firewall. They used a more abrasive matierial that made the metal feel almost like sand paper. They said it will make paint stick much better.
I want to cover the bare metal before it rust but i have to replace the front section floor pan. Should I wait until i cut and weld in the new peices? Im afraid if i use POR 15 and then cut out the pan then replace it, then repaint that section, i will have problems cutting through the tough paint.
