Build Information

Paint Colors Used

Mopar Slant 6 HyperPak Engine (Not used in this build)

Following are the colors I used on this engine:

Some of the parts are extremely small and I lost the oil filler cap and the vacuum advance valve in the Bermuda Triangle under my bench. I made a new oil filler cap from a piece of Evergreen 0.080"/2mm rod.

Mopar Slant 6 HEMI Head Turbo Slant 6 Engine

Following are the colors I used on this concept engine:

The piping that came with this engine doesn't make sense to me, in that I can't figure out how it can be used, especially for the air injection side of the turbo. One of the two pipes that came with the kit can be used for the exhaust side of the turbo. To make the air injector pipe I used a piece of Evergreen #212 0.080"/2.0mm rod.

Proposed Colors for this Build

I thought I'd paint the body burgundy and the interior either light tan or beige. I paint with water based acrylic for everything because my spray booth has no way to be vented outside. After a long search, the only paint manufacture I found that has burgundy is Mission Model Paints. I've used Mission Hobby paints in the past and found them to be fine, but very finicky with getting the ratio of paint:thinner/ reducer:polyurethane intermix correct, along with airbrush air pressure. Also, because of the Mission Model paint chemistry, their thinner/reducer, their polyurethane and their primer needs to be used so the correct chemical bonds are achieved. I'm Okay with that because I stopped mixing paint brands and additives a long time ago and have been sticking to using all products from the same manufacturer. Mission recommends using a ratio of:

Before I remembered that ratio I decided I would prime a couple of test spoons with grey and black primer. I added the thinner/reducer to the primer and apparently used WHY too much thinner because, although the paint sprayed well, it started beading up a-bit on the spoons. I left it go because it would be Okay for what I was trying to do, but I also knew I'd have to look up the correct ratio's when I do the actual painting.

I didn't have burgundy or beige in my Mission Model Paint stash, so I order a bottle of each through ebay. The day the burgundy paint showed up at my door we, here in Eastern Pennsylvania were in a very cold weather cycle. Temperatures were in the single digits during the day and negative at night. I was worried that the paint might have froze, but when it came I shook the bottle and it was thankfully still liquid. I left the paints set for several days and then went to use them. The beige was very thick, even after using the Mission recommendations, but it sprayed on the spoons very nice and very smooth. It clogged up my airbrush so I had to tear it down and clean it before using the burgundy.

I mixed the burgundy in the prescribed ratio but I noticed the paint just didn't look right when it was coming out of the bottle, but hey, I never painted with burgundy so I thought maybe this is what it looks like out of the bottle. When I started spraying, there was no color coming out of the airbrush. The only thing that seemed to coming out was the thinner/reducer. I emptied the airbrush, tore it down again and throughly cleaned it. I made sure the inner workings of the brush were fully dry and tryied the burgundy again with the same results. All I can figure is that the paint must have been frozen at some point in it's travels. It was at this point I decided I would not use Mission paints on this build, but I still want to paint the body burgundy.

I made the decision to use Tamiya acrylics and Vallejo paints. I looked up what colors are needed to make burgundy and found the following recipe:

I have Tamiya X-7 Red, x-4 Blue, and x-8 Lemon Yellow, and decided to try it out. I mixed the colors using:

That ratio did not work well. The paint was very dark and did not look anything like burgundy. I tried several other ratios and finally came up with what I think looks like burgundy and a color that I like:

This color is actually nicer than the original Mission Model burdundy. With this success, I decided to use either Tamiya XF-55 Deck Tan or XF-59 Desert Yellow for the interior. I hadn't primed the parts that would be painted using Mission Paint because I would need to use Mission primer, but now that I'll be using mostly Tamiya and Vallejo paints I finished priming everything using Vallejo 74.615 USN Light Ghost Grey primer because I fine this primer works as well with Tamiya as it does with Vallejo paints.

Following is a list of parts and the proposed color(s) of each.

TAMIYA ACRYLIC

Vallejo
