I took a piece of plastic trim off of the refrigerator door, and the snap tabs broke right off. Dang it!
The piece was marked PP, polypropylene, which just can’t be glued. So I used spin welding to reattach them.
I cut a thin strip from a plastic lid marked PP and chucked it in the Dremel. Spun it up and worked it into the fillets. Friction melted it right in there, welding the tabs back on.
I put it back on the door and the tabs are holding on tight. Perfect!
