As I'm working through the car and getting everything prepped for paint, I've been purposely ignoring the rear trunk lid. There is a lot of flex in the middle of the lid skin that oil cans / tin cans when you push hard enough on it. On the underside, there is no webbing or support for a fairly large section of the trunk lid skin.
Is this amount of flex normal or do I need to shrink the skin? I'm afraid that I will make it far worse by trying to shrink it since it is such a large area. Here is a quick video showing the flex: Link to YoutTube Video. |

Hey Guys,
The last 914 I did, the deck lid oil caned So bad it was difficult to block sand primer With out the metal popping down. After looking at the support braces on the Underside I noticed they were not actually Touching in back part of the lid. I turned The lid up side down on flat surface, hammered Edges of support down with dolly. This Brought the support real close. I then cut Strips of Dynamat Insulation, placed between brace And inter skin(not to be seen) It greatly improved, And blocking was not a problem. Hope this helps someone Bruce Attached thumbnail(s)

Hope this helps someone Bruce I essentially did the same thing, turned the lid upside down and got the braces to fit a closely as possible to the skin and then filled the gap at several points along the braces with panel bonding adhesive and then turned the lid back upright and made sure the skin was not "oil canned" down. Once the adhesive was cured the skin was rock solid and easy to sand without it popping in and out. |
