The welder works well and the temperature control is great. Allows you to dial it in and not overheat the material. I know this kit is sold to fit bumpers but different attachments would be a great addition. I will most likely be making some custom attachments to work on smaller and narrower parts. Used it to repair several interior parts on a 30 year old car. The higher power really helps with thicker material and allows for a smoother finish after blending the sides of the crease.
