    Putting 78 door panels in my 71 and 6 of the 10 fasteners are the two part type, metal post in door panel and plastic plug in the door metal. 1/4" close cell foam insulation is to thick for these fasteners

    How thick can insulation be?
    What is good for noise reduction? Give the door a more solid sound when closed

    I used second skin sparingly then used 1/8" CCF. I originally also had 1/8" foil thermal barrier but had to remove it because like you said, it was too thick.

    Thanks for the good info. Now I have numbers (thickness) to work with instead of trial-and-error

    Can you provide some detail where on the door panel you applied second skin?
    What brand of 1/8" ccf did you use? Does it have an adhesive backing? Why did you use ccf on top of second skin

    As part of my door insulation, will apply 1/4" ccf to the GM door concave stamping. Tested earlier in the rebuild and it made a noticeable improvement
