I bought the 12117 alum rubber coating for lining my 1960 T-Bird flooring. I plan on painting the floor before I put this insuklation I bought from you. I don’t want to do this twice. I need to know what I need to do next after painting the metal floor. I noticed when I stripped the old flooring that there is a lot of tar paper I scraped up. I noticed that there was double padding on the floor where you put your feet. Should I put that Insulation I bought twice as thick in this place.?? I also need to know what to do on the doors and rear quarter inside.
If you can help me so I can do this right the first time.
