If it is new/replacement floorboard, be sure to fit it in place first. The reproduction I got for my '41 coupe took a bit of pounding, bending, and grinding down the corners for it to go down tight. The pedal holes had to be reshaped, and the dimmer switch hole was in the wrong place, due to difference between '41 and '42 - '46. Then it got painted with black rustoleum.
