Need to know the best way to get off pre-applied red tape off my truck without hurting the paint.

hair dryer,keep your distance and keep moving around area, use a plastic
putty knives and when edge start to change, use knives to remove.
simple. but again do not stay in one spot too long!

I've had good luck with naphtha (lighter fluid) removing various kinds of adhesive, including old weatherstrip gunk, without damaging paint (old GM 'Magic Mirror' laquer, in particular; haven't tried it on '90s-and-up paints, though---you may want to try it in an 'inconspicuous location' first). A downside is, it evaporates quickly and has to be repeatedly applied, but you won't have to worry about where the hot nozzle of the hot-air gun is put down.

3M makes a rubber wheel that fits into your drill chuck for removing vinyl pinstriping (called a Stripe Off Wheel). Costs about $25, but it works slick and fast with no damage to the paint. I've leaned on it good to get some real old striping off and it still came off clean.
