Rebuilding the heater and AC Box today on my 69 chevelle. The foam gasket on my defroster door has expired completely. I went the the local home center and purchased some self adhesive PVC foam 1-1/4" x 3/16 weatherstripping. I got the Idea from this forum. I stuck some on a piece of metal and put it in the oven at 150 degrees to simulate the defrost heat. The weatherstripping got soft and when touched lost it's thickness permanently. Please help with advise on best type of material to gasket my defroster door and best method to attach. Thanks for the help.
