Did a little more with the trunk tonight. I did get the rest of it cleaned the other night and started to strip it tonight. I decided I am going to scuff the rest and use POR-15 Floor & Trunk kit on the trunk next Summer when I finish the bottom floor.
The rust has pitted the metal, but hasn’t rusted through so I won’t need to replace the trunk. The drivers toe area was kind of like this and I used the same thing on that area with good results.
