A bit more progress:

Dragon:
As mentioned above, the fuselage has been glued together and the fin aligned and the leading edge reshaped.
On the underside I filled the seams with super glue and sanded them smooth.
I did the same with two sink marks under the nose and a fairly large warped section of the lower aft fuselage.
The engine to wing fit is probably the worst part of this kit. The lower cowling seam needs to be eliminated, the fit of the rear cowling needs some attention and the fit of the engines to the forward wing is poor and needs some reshaping.

Hobby Boss:
I haven't glued the fuselage together yet. I'm deciding if I need to better clean up the area in the wheel well where I removed the slots that were to accept the cockpit tub tabs.

I've only attached the engines to the lower wing so far and the fit was good.
Dry-fitting the upper wings indicated that these will attach to the engines nicely too.

All are looking good. You will probably be burned out on 262's for a while.

G'day Spiros,
I used Roket Odourless Cyanoacrylate which bonds in 10-20 sec.
I lay it on fairly thick, depending upon the size of the crack or sink mark and let it dry.
Then I use a metal file to remove the glue down to the surface level and then sand to finish.
I do tend to take a bit of plastic off as well when I use the file.
I still need to re-scribe lost panel lines on the Dragon kit.
Using the file limits this technique to convex or flat surfaces though.
The advantage is that you can ge a very hard and smooth surface.

I did fill gaps in the aft engine cowl with super glue as well, but quickly wiped off the excess and cleaned it up with a scrape of a knife blade when nearly dry.

Best of luck trying it yourself.

I have tried filling with super glue, but don't tend to use it much. The trick is not to wait long after applying it to sand it down. I usually wait about 30 minutes. If you wait too long, the super glue will cure harder than the plastic, which makes it tough to sand without marring the surrounding surface. I tend to use regular filler which stays softer than the plastic. I think with practice you can get great results using super glue as a filler, as your work attests. Modelers that I know who use it regularly swear by it.

I haven't made a lot of progress this week because I was working on another build...
It is a RAAF Hornet painted with an Indigenous theme "Worimi".

That's a great scheme, Michael.
The artwork looks complex.
Is it a decal? Looks painted...

One of the beauties of taking pictures is that you sometimes notice details that you missed by eye. Hope the carpetmonster will be willing to let go the seatbelt! No matter how small, the posts are seen so keep them flowin' - thanx for sharing.
