I tell you, it's getting close to being used as a target, or a football !
Anyway, so far so good, the first lot of filler is on and roughly smoothed out, and is almost ready for sanding. Just waiting for it to fully cure. All the rough areas were filed first, followed by sanding, and it's looking hopeful.
Here's the same areas as shown previously, with the Italeri putty on the small areas, and Milliput where it needed to be built up and shaped. If all goes well, I might be able to continue with construction - if the parts will stick of course !
