Thank you, gentlemen for your comments - replied to in order below.
George, thanks for the tips. I will certainly pick up those sponge triangles. Thus far I had only checked out the beauty products section of the drug store for fine nail filing boards (for canopies) and tweezers. Right now I am using scraps of sponge from the lining of an airbrush box for masking etc. I also appreciate the tip about the storage box for dust protection. BTW, lately I have been running a hepa filter air cleaner in my work area prior to and after airbrushing. It really seems to have cut down on the dust and hair.
Thanks, Spiros for the chipping feedback. As you can see below some salt bits are already flaking off, which is looking good at this stage. So far no major worries. I am in no hurry to remove it all until the hinos and stripes are done.
Thank you , Erik for wishing me luck (as requested). I have no doubt luck is a factor with so many things at play in the finishing process.
Thanks for your careful observations and comments, Louis. I am feeling quite pleased with the look of the paintwork at this stage. One thing about painting on the markings is that you don't have to wait for decaling to see how the color balance will turn out.
Here are a few pics of the work on the wing hinos and touch ups in the fuselage. Before anything else, I had to lower the demarcation line of the fuselage camo. The green area needed to be lowered before I could do the fuselage roundel (a mistake in my original masking). The pics show the masking on one side and the respray on both sides, I exposed the repaint area up to a panel line to take advantage of any color shift as natural panel color variation.
It worked out well in the end.
Other pics show the way I fixed the hinos on the wings. I joined together strips of wide masking tape to cut the circular mask. The centre disc was used to position the surrounding mask precisely.
After fitting the final mask, I peeled away the centre part.
I learned from my Betty mask errors and used only Tamiya tape positioned at right angles in two layers to hold the mask together.
To avoid overspray, paper masks were added to cover the wings completely (with further Tamiya tape angled at the corners).
I sprayed in very fine coats of Tamiya Flat Red to avoid flooding the mask and causing it to lift.
I managed to avoid any bleed through and also achieved some nice tonal variation in the red, so I am happy.
As mentioned above, you can see bits of salt flaking off after being disturbed by the mask. This is fine but I won't disturb the rest until major painting is done and just prior to gloss coating. Hope you like the progress. More updates soon.
