Porco Rosso - Savoia S.21 (1/72)

No way I read blah blah blah zenrat AND Old Wombat BOTH said it'd be fine...   

Good tip on the off-gassing though.  Perhaps i'll Try to make sure I put down as many acrylics as possible first though.

Conversely you could dab your finger on the paint.

If it doesn't stick and show fingerprints afterwards, it's dry........................

But don't bet on it!

Ok.  So it's been a bit of slow going on this one as I've been tied up with a rough patch with some of my other build projects and I didn't want this one to get caught up in the mayhem.  I was also at a bit of a loss as to how to proceed with the painting even though EVERYONE said it was going to be fine...

So, instead I just filled in the seams with some putty.



But now it looks like the next step will involved paint of some kind.  So to that end, I decided to try my hand at decanting some Tamiya TS-12 spray (or is that 8? the Italian Red one anyway) into a small Tamiya jar.  The two-part reason for that is a) using a spray can fills me with dread given the scale and precision I'm hoping to achieve.. and b) now that the weather is cold I have no option for spraying off the balcony and I'm worried about fumes/overspray from my tiny little makeshift spraybooth.  I'm still a bit worried about the fumes, but at least with an airbrush I'll have a lot more control over what's about to happen... I hope.

Anyway, after getting freaked out by some of the online tutorials, I just decided to go for it.  I taped over the mouth of the bottle, cut a little hole for the straw, attached it to the spray nozzle and let 'er rip... and... I got a little bottle full of thin red paint.

Most of the online line tutorials warn against agitating (or even touching) the bottle until after all the propellant has been de-gassed (which happens once the paint reaches room temperature).  Strangely though, mine didn't seem to be the least bit put out by the ordeal. I carefully lifted the bottle like it was full of nitroglycerin... and nothing.  Not even a bubble or a hiss.  A little anti-climactic if you ask me... but I left the top off so it could de-gas while I'm at work today, just in case.

Hopefully I don't come home to newly repainted walls in my work area...

You can accelerate the de-gassing by screwing a lid on, shaking the jar and then very slowly unscrewing the lid a fraction - just enough to release pressure.  This is however fraught with the risk of unscrewing it a fraction too much and letting out paint with the gas.  Foaming paint that runs down your fingers and drips on the floor.

I'm glad Ispent the times to decant the spray can.  The Italian Red really makes this one.  It's soûler than usual going, but i'm Taking my time with this one (in and around other projects) to get it right.  I've spent more time removing the seams on a kit that fits like a glove than I usually do with the ones where the parts fit like they were designed by two separate blind people...

From what I've read & heard enamels can take weeks to months to completely out-gas; lacquers are faster, taking days; while acrylics are even faster, generally being completely dry within a day.

It's generally best to use slower out-gassing paints over faster out-gassing paints - unless you're willing to wait the required full drying/out-gassing time before coating over the previous coat.

DISCLAIMER: All paint drying/out-gassing times are affected by temperature & humidity, & even whether they're matte, semi-gloss or gloss. Lower temperatures, higher humidity & greater gloss increase drying/out-gassing times (sometimes quite considerably). If you can detect even the faintest odour of solvent/paint, it's still out-gassing. Once you can no longer detect any odour give it another hour or two for acrylics, a day for lacquers & a week for enamels. (Note: This is the "very safe" version, which I rarely follow but should - it'd save so many hours of paint repairs! )

Lacquers dry through solvent evaporation, enamels cure through exposure
to the air, very different chemical processes.

What's the difference?  I'm guessing curing is a chemical reaction between something in the atmosphere and something in the enamel?

Yep, oxygen.

So the paint is oxidising.  Which doesn't sound anywhere as good as curing as we associate oxidising with rust and patina.

Hi all.  It's been a while since my last update - a combination of a Christmas vacation and the pile of work waiting for me on my desk after I returned.  I'm starting to get my head back above water so I've been able to take a few pokes at the 'ol modelling bench.

I actually got this project done just before Christmas, but I didn't have time to take some proper pictures of the completed build until now.  I was too lazy to set up the white background I usually try to use for the "final glamour shots", so a semi-clean workbench as a backdrop will just have to do.













As others have noted, this kit falls together like a dream.  On the good side, I was happy that I decided to decant the Tamiya TS spray and apply it with the airbrush as well as ditch the decals and paint on the green/white Italian colours.  I think it came out much for the better.  However I did have some challenges after I ended up getting a bit of spill-over of laquer thinner sloshing under my tape dam and destroying my meticulous interior paint job, but some careful taping and re-painting has salvaged it suitably.  I also had a bit of trouble with the extremely simple rigging for some reason.  I don't know what it is, but I get the shakes something fierce when I try to attach little cables anywhere and I seem to apply CA glue like a interpretive dancer.

I'm also relatively happy with the canopy, which is 100% scratchbuilt.  I did end up getting a bit of white glue in places I didn't want, but was able to clean it up a bit .  It's the one downfall of an otherwise stellar kit... a windscreen made out of 1/72 scale public aquarium glass.
