My 1974 914 has the typical bubbling paint on the rear trunk lid due to rust caused by the foam insulation. I have cut out a section on the left side of the lid and removed the foam to treat the rust. Should I replace the foam with something else to give rigidity to the lid? Also, should I go ahead and do the same thing to the right side of the lid, even though there are currently no pin holes there?
I am stripping the car for paint--my first experience. Thank you for any suggestions or experiences.
