    Dean,

    I’ve used the yellow stuff in red can available from Home Depot or Lowes. Do it in two applications which allows you to spread it around with thin coat first. I used a wooden paint paddle and an old pair if gloves. As you watch the expansion you can judge the thickness you need. If you have not used this product before I would suggest a trial application on a piece of card board.

    Let it expand and cure overnight.

    With a heavy du ty blade knife that won’t bend …..trim high spots. A second application will give you the flow matching the existing foam.

    Let cure overnight, trim any high spots next day.

    With flat black color rattle can spray your repair. After you drive in the next rain storm it will be a perfect match.

    This foam question has been asked before, member wrote about a kit available with everything you need to repair under carriage damaged foam.
