Hi another quick question, I am wanting to coat the floor pans inside my car with extreme chassis black. I have got some of the panels down to bare metal where there was rust and have treated them but a lot of the paint inside the car is in decent shape just old. I was wondering I could could just rough this paint up with some sand paper and clean it with PRE and spray the chassis black primer right over the old paint/primer before I lay down the thermo coustic.
Thanks again in advance
