Those are great improvements to speed up productivity, Carl @clipper
Even though the amount of produced builds is not the most important part of modelling, you still want to see some progress and results achieved over the year.
The plastic containers are a very good idea, will have a look around for something similar.

Everyone builds at different rates, Carl (@clipper). I really depends on what else is going on in your life, how much time you have to model, and how much time you want to model. Now that I am completely retired, the number of kits I build has increased significantly. I only build one kit at a time, so keeping kit parts together is limited to one kit at a time. It always seems like modeling is a case of hurry up and wait. You do some work on the model, then wait a day for stuff to dry. I have a model train layout, so I work on the trains while stuff is drying.

Looking superb so far, my friend @clipper!

Wow, Carl (@clipper). This marbling will certainly generate a weathered surface. I always have trouble pre-shading, so I am looking forward to seeing how this comes out.

I've spent most of the weekend (when I wasn't doing other things) painting the Mustang and the moving the Constellation along. I continued to paint using a process I started using on my A-20, namely, painting the secondary colors first, then touching up the black base and marbling after masking off those secondary colors.

I like this approach for two reasons. First, I can use the black base and marbling under these secondary colors, and secondly, it eliminates and odd shading from painting over the primary colors.

Painting on the Mustang is nearly completed. I have one spot on the O.D. where the airbrush spit a small amount that I will need to touch up. I was nearly done when that happened. I hate it when that occurs. The neutral grey on the bottom was lightened from the Tamiya XF-53 because it would have been too dark. And the O.D. was a mix of Tamiya Olive Drab, Flat Earth, Flat Green, and a small amount of white.

I am going to mask off the flaps and wings and paint the interior of the flap with an interior green or chromate green. Not sure if that is correct, but it is only a small exposed area and I hope it will look okay.

Great progress, my friend @clipper! Mishaps happen to me all the time, so, if nothing happens, I get worried 😄
Your touch up Idea is nice.

Thanks JOhn (@johnb), Spiros (@fiveten), and George (@gblair). I am happy with the way it turned out so far. However, one thing I don't have a good solution for yet is what to do when this type of mishap occurs and I am using a custom mix of paint.

Storing the mixed paint colors in a jar has several disadvantages. First, it's difficult to know how much you might need later and can be wasteful of paint if you mix extra and then never use it or it might set for a long time before you need it again. I haven't found a glass mixing jar jet that will keep paint mixed this way fresh enough to use some months later. And additionally, it costs money for these jars. I have started saving empty Tamiya paint jars which alleviates the mixing jar cost, so there is that option. But the main issue is the extra paint used which may go to waste.

Another issue, is that I normally lighten colors as I paint to get the multi-toned appearance, and it is impractical to store mixed copies of all these various shades. This may not be too big of a deal.

I am just trying to find a system that is easy and which works every time for mixing custom colors.

I am inclined to start using AK Real Colors or MRP or Vallejo paint sets, but I really like the way that Tamiya paints work. I just purchased some color test cards that I am going to use to brush and spray custom colors as well as different shades of paint from the manufacturer. The custom mix cards will have the formulas. We'll see how that works out.

Yes, my friend @clipper, mixing colors and storing the remain is a challenge.
