Oh, you mean the hard way? Without prepunched holes? Like they used to do on the 3/4/6?

No, using an existing sheet with pre-punched holes as a template is way easier...

"Used to do?" Heck, we STILL do it that way.

You betcha...
Making new skins from scratch is easy when you have a flat template like that. Compare the prices of new stock to Van's plus shipping. Sometimes Van's is cheaper, other times Spruce is cheaper.

All is not lost. if you scrap that skin you can use it later for other things.
I scrapped a skin and I have put that old skin to good use.

I missed with the deadblow hammer while dimpling one of my wing skins. If I remember the part from Van's was around $65 (2006) which wasn't much more than buying aluminum sheet. Shipping would have cost quite a bit so I just had them ship the new skin with the fuse kit.

This is pretty much the decision maker for me. I'm on the fence for now, but long-term it might well bother me. But more importantly, my copilot was quite clear that she would be concerned about the skins.
In the grand scheme of the build, $200 is pocket change for peace of mind. I guess I'll have no shortage of scrap material now...

Van's Confirmed 10% Rule
I had some pretty serious surface corrosion spots on my wing skins when I bought a second hand kit. I emailed Vans and they said I could remove up to 10% of the thickness. An hour with scotchbrite, sandpaper and a can of primer and it was fixed. I did check the "deep" spots with a micrometer. Despite my fears, I had only removed 5-6% on the worst spots.
I was lucky enough that the corrosion started under the blue vinyl near the edges so I could easily measure. I can't tell from your pictures if it's near an edge or not.

It's not...pretty much in the middle of the skins. The pictures aren't really great, but I made this thread as more of a lamentation of my stupidity than a serious inquiry about whether the skins were salvageable.
Your corrosion repair makes me even more convinced that I should get more skins; if you took off 5% with that, I suspect I'd easily approach 10% sanding these out. The scratches are pretty impressively deep.
