i have a red strip on my vs ute that i want to remove, but i dont know how to remove it with out leaving marks or bits of glue and damaging the paint
Derp tool done the trick for me. Make sure you use a left handed drill. The right handed ones spin the wrong way and are less effective.
Also standard drills don't really work too well so if you drop by mitre 10 or bunnings ask them about their drills with forced induction, they will definately do the trick mate and theyre fairly cheap for what you get, if you have any more problems just ask.
angle grinders also work too well. and then use a belt sander with 40grit paper to finish it off. (if you havent figured there is a thread in the how to, to your problem)
