[NOT A TA]

I shot some epoxy primer and then some high build primer on the inner filler panel and then did some prep work on the underside of the filler panel as well as the rear seat firewall I'd welded the panels in. Then I shot them with some red epoxy primer that kinda resembles the original primer which will show in the trunk in some areas after splatter paint gets applied giving the trunk a somewhat stock appearance. I know it seems silly "restoring" the trunk area appearance of such a modified car but it's what I want. I even have a reproduction trunk mat I use unless the cars getting raced or tracked.

I made a panel to cover the rectangular opening in the package tray I haven't installed yet and am still considering options to cover the speaker holes during track/race events to complete the firewall between trunk and passenger compartment.
