I got bored last night and revised my trunklid extension AGAIN! I got tired of looking at it sagging and the tape not holding it up properly, so I ripped it off and cut a fresh piece of coroplast, 1” longer than the last one, and about 1/2” wider than the last(it never came to the edge of the trunklid)... I also measured and cut some bigger reinforcements and added side plates for a “sort of” box cavity...
More over, I used hot glue for most of the seams where the coroplast goes together, and drilled directly into the plastic end plate of the trunklid (it’s a Saturn thing lol), which means it isn’t held on with strapping tape! I feel so grown up lol...
