Top Secret PDR Blue Jay Blue Glue. This glue is made for use in the removal of Dents from automobiles. Best panel temperature 70 degrees. I have been finding this glue compliments the Ice tabs And has been doing an excellent job on smaller tabs and pulling hail dents in the rails. It works well on larger tabs as well and cleans up easily. These sticks fit in a standard glue gun NOT in a craft gun. Again these glue sticks fit in a standard glue gun 7/16” or1/2” in STANDARD glue gun for professional use only if you are not trained in glue pulling leave it to the professionals. PDR is not a do it yourself thing.
