Looking for insight. I have a 55 4d, 235 99% original and trying to keep it that way as much as possible. But it is NOT a show car, just wanting it to be very nice to the original. I need a radiator but having a had time dropping $700 plus for cooper and brass. I see some aluminum ones that are shaped like the original and i see that some have painted the top black like the original. Has anyone had experience painting an aluminum one and it lasting and looking good over time? Thanks for any info.
