Better use modeler's knife to cut straight without sanding.
i feel sanding is waste time and surface no longer shine.
Try practise ur cutting skill, can on stroke cut off those nipper point and left smooth and shine finish.

Nice! btw no decal?

Use zippo lighter fluid, for ratio you need trial and error.

If you're still not confident about mixture ratio (honestly, mistakes are the most effective way to learn), try Valejo air paint, it's already prethinned and ready for airbrushing.

basically, yes. but godhand has some limitation, cannot cut thick runner otherwise you risk ruin the cutter since the blade is very thin. Normally recommended that u use your current nipper to cut til few mm left, then trim with godhand. I am using Wave cutter, also very similar, 90% of the time no need to make additional processing to nubmark. If i feel picky i'll use very high grit filer to file the surface so that it looks very smooth without cutter streaks when u look closely
