I have the same issue with trunk lid fitment as many others have found; the curvature of the lid doesn't match the body. It's high in the middle by a good 5 or 6mm. I've tried leaving the lid in the hot sun for a few days with ratchet straps pulling it into shape, but after a few days without the ratchet straps it just reverts back to the original shape.
I'd love to get Tim's insert bars but it's just not cost effective to ship them to Aus, so it looks like I'm going to have to make them. Can anyone share any wisdom on the right material to use? From what i've read, steel is not ideal due the difference in thermal expansion with glass, and it'll rust. Aluminum appears to be the best choice, but will it be strong enough to hold the required shape? I'm thinking something along the lines of 10mm thick aluminum plate cut to the right curvature and around 10-15mm wide (whatever the distance is between outer & inner skins), installed and bonded in place on it's edge.
Thoughts?
What's a suitable product to bond in place?
