My Dart Swinger Project!

I wonder how much it would rust if I went ahead and started sanding and blasting it to bare metal in three weeks time?
Yes that's the color I was thinking of, like your choice! Glade to hear you are still working. If you get it down to bare metal get some primer on it right away, even then primer will start to have surface rust issues. Most primers are porous, to help give paint something to grip to, so it also wants to suck up moisture like a sponge. Epoxy is the way to go if it has to sit for a length of down time...Keep us posted enjoying your thread.
