Been there, done that, works great.
Did the entire floor, interior firewall and inside steps on the 59. What shows looks close to original, easy to clean and tough as nails. I used the Duplicolor roll-on and the spray for hard to reach areas. Available at WalMart in Qt and Gallon cans for the roll-on.
