It's about the same as any other paint, but there is no exact ratio. Some colors want more/less reducer than others. You can thin them with hardware store thinner, but for the best flow and gloss the Tamiya brand is the way to go.
No special cutting tools were used on this, it's more about getting the cutting angles where I want them. I was able to make it with what I had on hand and didn't even use a compound slide.
I reworked one of the kit knock-offs and used it as a master and cast four new ones. Tamiya lacquers for the color, aluminum powder for the light shading to enhance the anodized effect.
The rear axle ends are blackened brass and the front spindle ends are machined aluminum.
This is the left rear and right front.
Finished scratch-built wheels with the kit provided tires installed.
The rears have the ends of the axles installed; the front spindles will come later.
These are the finished Auto Meter gauges.
The water temp and oil pressure are mechanical, the tach, fuel level and volts are electrical and the speedo is an electrical GPS unit.
More scratch-building... Left and right side dash panels. The vents are brass and aluminum with PE screens. Rivets are steel. Glove box door handle and gauge bezels are aluminum; gauge housings are brass.
I wanted to mount the lights to the forward structure for easier final assembly after painting. A new set of mounting brackets were fabbed up and the original light housings were reused.
The driving lights did not align well with the openings in the body. I also thought the openings looked bland being just holes in the nose. I machined two tubes from aluminum impregnated resin and faired them into the nose. This should also help to reinforce the nose where it has been cracking. The inward facing openings of them were shaped to accept the lights.
