I continued my work on finishing the fuselage.
To begin with, I lightly sanded the coated fiberglass with 320 paper.

I then used a professional car sealant to correct the last few flaws.

and then a coating of the same brand. The fuselage is starting to look like an airplane. I like it.
Well, there’s still a few flaws that I chewed out last night, though. Sanding tonight if all goes well.
I weighed everything after those steps. I’m at 805 grams, which is 28 grams more.
In total, the nitrocellulose coating, canvas, putty and filler weighed about 60 g. The paint and a few drops of rivets remain.
