This trim piece will also get some work done to it. These parts will be a great test for our plastic weld compound.
This is a very clean break that I taped up from the outside to begin reconstruction from the inside.
I put some adhesive in the joint to prime it and hold it together initially. Then I just put some powder on top of it and added a couple drops. The bond happens very fast. After a minute I sprayed the area with the accelerator that is provided with the kit. Supposedly the liquid chemically removes the oxygen which causes the adhesive to harden much faster than without.
I did not use the dremel to make a groove along the outside of the crack. The adhesive bonded well to the perfect crack and left the surface nice and flush.
