65 Dart GT Project Started

Beautiful car. Mine is also a yellow 65 Dart GT, but 2 dr hardtop. I don't have your tools like the rotisory or sand blast, so I used just a drill wire brush and crawled underneath and inside the trunk. My main mistake was not disassembling everything first. I worked around parts that I later removed, especially under the dash. My suggestion to anyone doing this is to pry under the "seam seal" in the trunk with a putty knife. Much of mine popped off easy, and I found surface rust underneath. I used PL1 polyurethane caulk to re-fill.

I am using Interlux Brightsides 1-pt polyurethane and so far painted just the difficult areas - engine bay, trunk and under-dash. The original paint was a bit too "faded yellow". The car had been repainted, so don't know how yellow the original factory color was. I used 3 parts white to 1 part yellow, but found that slightly too yellow (but much lighter than yours). I will go with 4 parts white to 1 part yellow for the outside. The upside is that the yellow is sold only by the quart and is ~4x the price of white.
