Editted new bit below...
You could always prop the nacelle pylon back into place, Bondo it, sand it, and repaint from scratch. It'd be cheaper.
Project 3 - Wesco Enterprise-E UPDATEI have bitten the bullet and sanded the deflector trench to a more canon shape.
In progress shot:
Cleaned up:
I stopped sanding at that point, because the corners in the trench were starting to wear through. I'll get myself some Bondo to sure up the inside, but it's close to the correct shape now.
I've yet to go over it with sand paper to finish it off, hence the rough look. Any tips for this type of work?
EDIT:
Project 2 (JJprise Aztec) UPDATEMore progress!
I continued masking the aft half of the saucer. I think i was a little drunk or something when I did the starboard side, some of the lines are a little skewy and a-symetrical. It's not too noticeable, but I wish I had done it better.
Anyway, I hit it with a couple of coats of sealant:
Apologies for the poor quality photographs from here on out, my old phone decided to stop responding to button pushes, so I've switched to a better phone, with a crapper camera.
Anyway, when the first few coats of sealant had dried off, I came up with an idea, to hit it with a thin mist of chrome spray paint - to imbue the aztec with a little extra specular reflection, aside from the gloss of the sealant. I sprayed the starboard aft quadrant first, just a puff, and you know what? It looked pretty nice!
So I went ahead and puffed the port side. SPLAT. The can sneezed a big burst of solid chrome onto the ship! ARRRRGH!!!!
Note to self: shake can well before each application.
Well, I scrambled to grab a cloth or something, chanting "********************!" the whole time. Eventually, I found a tissue in my pocket and dabbed at the model. Luckily, the last coat of sealant was in fact not dry at this stage, and the chrome was merely floating on top. Most of it came away, but it's dry now, and you can see the difference. I stripped the tape off - a process that took longer than the masking took to create... almost.
There is only 3/4 of the forward starboard quadrant left to mask and seal. I'm so pleased with the chrome effect (starboard side, anyway) that I intend to re-mask the port forward quadrant and chrome-mist it too.
Check it out:
I made this Gif just now to illustrate the specular properties of the aztec. I took two photos, with the phone stationary, relative to the ship, but having twirled around between the two, so that the lighting is different. See how the hullplating reflects the light differently:
I realise this emphasises the over-painted port side, but that's only because those were the only photos that lined up this well. The light-dark dichotomy works just as well on the starboard side, which I think you'll agree, on the evidence of the flat-light pic up the page, is much more subtle and effective.
For a ship design that I'm really still a but iffy about - I can't put this toy down today!
The Aztec doesn't always jump out at you, it blends into the hull colour well enough.
Anyone got any ideas on how to bring the aft port quadrant in line? I was thinking a light airbrush coat of colour-matched paint, to bring it back to the hull colour?
