What am I doing wrong ?

Aluminum, 5 pieces. I used 2 20" lengths of angle Iron screwed together and washers between them making a gap the width of the aluminum then clamped in a vise to make the bends hammered over. Spray glued the material to the pieces then pop riveted them together. The material is like used on speaker boxes I also used on window frames, doghouse, dash, etc.

"...seals/hides the seams and rivets~
What is it?
(1 asks the liner material, nother asks the metal of the DIY box itself...)..."

Possibly no responses, only statements here~

FYI...

I was finally able to get time to test fit a new glove box door (this is busy time at work, much overtime).

The new door took care of the problem...

Thanks dix !!!

your welcome glad i could help...
