It's amazing how the penny can suddenly drop! Because of another aberration I recently uninstalled 'Snap Do' which apparently was linked to Chrome. Whatever a re-install of Chrome has got the album back up so lets have another try
First off was to do the fin. This is a French subject and apparently these were coated on lower surfaces with a moisture resistant coating that gave a blue hue to the ally. On the very few pics I have this appears to have been applied to parts of the fin too so this will be my interpretation.
I prefer to cut 6-8mm wide strips from the 40mm wide Tamiya masking tape as this lessens the pull on the paint on removal. Kitchen foil makes an excellent, easily wrapped around mask too. The brown tape (name escapes me) is no longer available but is the best used so far - fortunately I purchased a few rolls sometime back. Unless its a small area as above it's usually reserved for edge marking only.
Next up after masking was to apply a coat of Dark Aluminium as a base. Incidentally, every coat gets a smoothing with 6000 Micromesh and water, wiping off with a Kleenex tissue. The difference is readily apparent as soon as you run a finger over the surface
The areas were highlighted with White Aluminium, then Polished Ali and Chrome to accentuate and the edges darkened with Jet exhaust and Hot Metal Violet. The initial staining was carried out with some of the new Alclad 'Candy Colour' dyes - yellow and orange
The blues and browns where then added but it was after this I 'lost it' somewhat so had to re-coat again. By that I mean just lightly over spraying with Highly Polished and starting back on the colours again.
The last stage, frustratingly having to be left over a week ago was a decision to mask each rivet line with a rough edged mask to give the differing tones at that point. The other side has yet to be done but I'm hoping that now I shall be able to have the continuity to finish this area
There's a lot more work to do to get this right as yet!
Incidentally - the 'rough edge' to the mask was made by laying down a stretched out straight cotton thread over a piece of glass then a strip of masking tape over the top smoothed down each side of the thread. A gentle rub with a sanding stick over the high point to create a weak point allows the cotton to tear the tape in a straight line but in a rough manner.
Hopefully that's of interest . With luck I'll have something more to show in a day or two
Regards for now - Tug
