Regarding fingerprints, on my first DeLorean in 81 I carried a spray bottle of vinegar and water just to wipe out the tons of fingerprints everywhere I parked haha! So this will happen for sure
When I bought my first DeLorean new in 1981 every place I would park people would touch the car - so many fingerprints so finally I kept a spray bottle of vinegar and water and had to continually wipe them off
