I presume both sides were sanded/polished approx. the same amount.
About the same amount on each side because the scoring was as bad on both sides. It's not super smooth. The thickness of most of the repair is about 0.030+ but there are a few thinner areas.
I'm actually going to delay ordering the new skin--might be able to live with this. I'm in no hurry to get the top skins riveted on. I think it's worthwhile to ask a local EAA tech counselor to have a look at the repair job.
