Well I managed it, although it took about an hour and a half to cut and apply the tape, after a couple of false starts. A minor problem when using very thin strips of Tamiya tape, is that it sometimes doesn't want to adhere very well on a matt-painted surface, and has a tendency to want to slide around, due to the minimal surface contact. Hopefully, I haven't disturbed any strips during handling!
So, the Medium Sea Grey has been mixed and sprayed overall, deliberately a touch lighter, to allow for some shading and the darkening effect of the following clear coats; the code letter masks have been applied, and the Dark Earth sprayed.
This was built up in a slightly 'patchy' manner, to simulate the effects of the Indian and Burmese climates. This aircraft had only been in service around a month at the time depicted, so weathering and wear would be minimal. However, the harsh conditions did make the Spitfires look somewhat dirty fairly quickly, especially in the dust of Rhumkhapalong, so a little weathering and wear will be added later.
Like Andy, I don't 'go in' for heavy weathering, unless of course there is evidence of this on a specific aircraft, as I personally think it is so easy to get it wrong, making the model look like a 'good model' perhaps, but exactly that - an exagerated model, and not a miniature replica of the real thing. This is especially true of panel and rivet lines, which in most cases, with some exceptions, can't be seen much unless literally on top of them.
Anyway, here's where things are up to at the moment.
PIC 1. The tape 'reverse masks' for the lettering, laid over the base coat of Medium Sea Grey. These are 9.5 mm tall, scaling out at approximately 18 inches, the size of the small code letters used. The space for the SEAC roundel will allow the two-tone blue roundel to be placed and aligned accurately (when the decals arrive!), the real thing being 16 inches in diameter.
PIC 2. The relevant areas of the underside were masked, and then the Dark Earth sprayed, built-up as described earlier. This was left for around four hours, before the demarcation for the Dark Green areas was lightly pencilled in. I noticed, whilst doing the pencil lines, that the paint still felt fairly soft, and had a 'dusty' texture to it, another example of the inconsistent, poor quality of Humbrol enamels lately. This was a brand-new tin, which had been shaken, and then stirred well, at least 200 times, before being decanted, thinned and stirred again, as per usual practice. It has also dried slightly lighter in shade than the previous tin, although this is welcome, as I wanted to start with a slightly lighter shade, and then add depth by spraying further 'mist coats' where required, around some panels, and in areas of shade.
I was hoping to get the first coat of Dark Green on tonight, but I think it's better to let the paint fully cure for at least 24 hours, before hitting it with the next colour, otherwise 'orange peel' or other nasties could occur. So in the meantime, I'll keep busy by making some stencil decals, which are not included on this kits' decal sheet, probably due to this being USAAF version.
Once again, thank you for the compliments, and I'll try to get some more pics posted tomorrow.
