Tool is made is China, but it seems durable. Seems like the only wear item on the tool is the polyurethane roller that makes contact with the fender. Then again, any tool can be destroyed if used improperly.
I bought this several weeks ago to roll the rear fenders on my Subaru WRX & Nissan 240. It does the job well, but it takes patience since you’ll have to heat the fender & adjust the tool multiple times.
Take your time, I got carried away at the first attempt and cracked the paint! 😡 Lesson learned: Heat the paint until it’s HOT to the touch.
