See the video below for a quick overview of flame polishing pinball ramps that i did a few years ago. Its really important to clean the ramps thoroughly, then polish will 1500 and 2000 wet/dry paper to take out any marks, after that (and you have double checked for no remaining ball trails), crack out the blowtorch and flame polish.
I find using a smaller soldering iron type blow torch is more forgiving as you have a it more time and can see it working, but you still need to be very careful as if you hold it in one spot too long the plastic will bubble and/or the ramp could warp.
