So tagging behind the previous post I thought I would show something that I've been wanting to show on this forum for years.
Using the servo hatches here. Previously you saw them primed. I coated them lightly with metallic spray paint. This takes FOREVER to dry so give it at least a few days to fully cure out. See how the rivet marks are more dull than previous?
So we start the process by simply painting the parts. I'm using Behr premium indoor latex paint here. The same can be done with acrylic paints. Using another spray paint over top of the initial spray paint... Its not really going to work because of how the molecular bonds work in spray paint. Stick to latex or acrylic.
Next we take some steel wool and drag it across the surface where you would expect the air to flow. So the leading edge of the panels and of course along the rivets. The rivets are flush but they will still see turbulent air. The wool will create tiny scratches in the top paint and reveal the metallic finish beneath making a very nice weathering effect. This can take a HUGE amount of practice to do right so be sure to practice. You can easily over do this. Airplanes never flew looking like they just came out of 50 years in barn storage. There is a little wear and tear but never at apocalyptic proportions.
From there, I sanded with 3000 grit to smooth out any blue overspray and dull the wool work a bit. It seemed a bit too harsh but I was happy with the amount of metal exposed.
And the flap hatches done as well. Notice how well the rivets are now blended in with the paint? They are present enough for you to take notice at a fair distance but not so prominent that they distract up close. It is a happy balance.
I love this technique and I would do it all over this airplane if I could keep the weight of two layers of paint. Perhaps a little could be applied on the front of the exhaust fairings. Just be careful as it is very easy to overdo. It looks cool, its easy to do,... WHY NOT DO IT?!
