Gap issue:
I am about to install the headliner. I just dry fitted the headliner and have discovered why some folks are having gap issues. The #2 forward and back panels need to be oriented correctly they may look uniform but there is a subtle curve and fit that can only be seen if you first dry fit them.
I labeled them so that is can orient them correctly once I am ready to use contact cement for the install. I am going to use standard Contact Cement for a permanent install.
The#1 Forward and Middle panels also have slight curve differences, that require them to be mounted in the one out of four possible ways.
There is a significant overlap on the all of the #1 and #2 panels. I guess carful trimming is in order.
I am going to just soften the edges with 220 sand paper. 1/2 inch round seems a little too much for me. I would rather make for a softer edge than to possibly eat up a panel with a router……
