So to begin adding plastic weld to the area I simply dripped a couple drops in the crack then sprinkled a little of the powder on top of the liquid. It's really easy.
Just add a few more drops and sprinkle some more powder and the cracks will start to fill with material. I used an acid brush to even out the powder. What also worked well was applying the powder on top of the drying adhesive and smoothing it out a little before adding a drop of two on top of it. This will make the surface a little smoother. The powder really soaks up the adhesive really fast so don't use much adhesive at all.
I then removed the tape from the outside surface since the parts are now secure and will not move around anymore. Then I went to work on the outside filling in the cracks. This was my first time using the material and I have since learned how to apply it to make the surface more even. But this is decent.
