I got the trunk finished today. I spent a couple hours soaking the plastic tail lamp housings in PurpleStuff degreaser to remove the fossilized remains of that roofing tar/rustproofing that encased them. I also pulled the tail lamp wiring harness out and masked off the trunk area.
I first used some red oxide primer to spray a small area at the inner, tops of both NOS quarters because they were still in their original black E-coat, instead of red oxide dip primer. I then sprayed the areas that were going to get the trunk speckle paint with dark grey sandable primer. This really helped with the speckle paint coverage. I was able to do the entire trunk with one can of the Eastwood Trunk Paint since the background dark grayish color was already there.
To get the right finish I really stood back a ways to get the spray as dry as possible when it landed. I was spraying from outside of the trunk opening most of the time and I used small one-second bursts with the can until I got enough coverage to resemble the original speckle finish that is still remaining in some areas of the trunk, such as the trunk latch bulkhead. I think it came out reasonably well for a spray can job.
