For those panel lines that are straight but too wide, you might get away with just brushing on a layer or two of surfacer, though the resulting depth will be shallower. The irregular line, best to fill in completely and redo.
I haven't had good luck re-scribing over superglue - it dries rock hard and when passing the scribing tool over two different surfaces (the other being the plastic kit), can cause it to jump, or after several passes, you might find the depths uneven - just be aware of that. Fine grade putty if you have it - coarser can tend to crumble.
----------------------------------
PE detail is complete for the most part, but still might scratch build a few things, like some remnants of the wading depth gear in the back end. This will require elevating the storage box at the rear to provide clearance for said gear, though I can't figure out why the bin seen in these photos is upside down:
I've also removed the spare tracks and have to redo this. Photos show those stored in the provided racks had the guide teeth removed, while the remainder had the teeth on backwards:
The only regular gear I left off the tank were the gun cleaning rods, though I did attach the clamps for them. They likely were placed in the rear bin. There should be a sledge hammer too, but none provided in the kit.
Still working on replacing the Tamiya tracks. I ordered a resin set, and though they have the more proper thread pattern, the overall quality is - well I'll just say I've seen better. I've emailed Shapeways.com (a 3D printing company) to see if they offer their Sherman tracks in 1/48.
