x2 on the Nason single stage. I'm on about 10 years on my daily driver. Seems like a tough paint. It is time for a refresh, but... Pretty forgiving to paint with. Definitely not a show truck finish but it looks good and plenty fine for a driver.
I used Nason single stage on the interior of my 49 as well, it turned out well and haven't had any chipping. Color might not be a perfect match after drying, but close enough for me. Haven't done the outside yet as someone years ago hit it with some red Tremclad rust primer type thing, which I think will have to be removed first if I paint it, but if I do I'll use that Nason on the exterior too.
