There's no "besides", get the 3m wheel. I've detailed professionally for years and that's my opinion. Plus it last forever, so it's worth the money. You'll use it on your next ride , or a friend's ride, or gf/wife , exc. I used it on several of my own vehicles, street bikes and snowmobiles. I've had the same wheel since I bought new in 09 when they first came out, back then I paid $40 lol
Use it on a lower setting, make sure paint is cool and in the shade. Start from one end and work your way to the other end letting it build up and majority of the glue will fall right off, the rest will fling all over you and your hands so don't wear your clubbing clothes lol.
