I did a cowl and hatch with Klass Kote. The finish was really nice. The color match was good, even with pearl blue, orange and white. Only 2 coats were needed with no need to clear coat, it was so glossy it looked like you could stick you arm in it. I did 3 colors plus the primer and it was less than a hundred bucks including a Harbor Frieght 15 dollar spray gun.

Another idea is to contact Radio South (Tony Stillman's company in FL). They have already matched up the monokote and ultracote colors for PPG single stage paint. The last time I ordered I think it was $40 for the paint, and another $20 for the hardener. You'll need a spray gun and also paint thinner for single stage paints. It doesn't require any clear coat, and the colors have always matched perfectly (but be sure to use a light colored primer).

Pete,
I bought the paint for my Dalton from Radio South.....it indeed matched perfectly. The price was closer to $200 for the primer, two colors and the hardners.

I have had real good luck with taking samples of covering to Napa or other places that mix paint. They can use their machine to match the colors. The last paint I purchased ended up costing about $20 a pint with the reducer mixed in ready to spray. I went with a one step paint and didn't use the hardner. End results were great and didn't have to spend a bunch of extra money on reducers and hardners. Went with an acrylic urithane paint.

Here is a few more pics of the plane(john Deere tractor) from over the pond. Needs cowl and pants painting,canopy cutting and gluing,and electrics sorting. The ignition was just strapped in so the engine could be tested.We use a place called B&Q in the UK take a bit of Oracover the color you want and they mix the paint, match is very good.

You could do yours in that scheme but maybe in Pink & Lavender...

You must be right; I'm probably confusing that with the CARF touch-up paint.

O.K. It's been awhile since I posted on here. Been busy with other things, company, family, house projects the wife wants, as well as doing a Pressure Load Test. Some of you may recall that I was going to try to do some testing.

I had some material in my stock of wood, that I thought could be used to make a test frame, in particular some finished 1 3/4" x 1 3/4 oak that I used for columns and a loading post. My initial thought was that I could use them with 2" x 2" x 3" foam samples, that would have 1/16" x 2" x 2" balsa glued top and bottom. That way, with the sample centered on the post there would be about an 1/8" hanging out on each of the four sides to take depth/height measurements with my digital caliper. I chose a 3" high sample so there was enough height to get a decent measure on the deflection/strain, without being too tall that stability or buckling would be an issue.

I think it worked pretty well, except that as the load got greater, I believe the sides may have had some bulging. All the samples had the grain of the balsa running front to back (Sides 1 to 3) The balsa in the orthogonal direction is much weaker. I believed the measurements on sides 2 and 4 of some of the samples were suspect. The most suspect were Samples E and G. So, they were done over again, and show in the attached photos as Samples E2 and G2. The plotted results show the average of the measurements on the front and back only (Sides 1 & 3)

With E2, G2, and J (the 640oz, 10psi) samples, a 1/8" x 3" x 3" steel plate was used above and below the sample. Then instead of measuring from the tops of each side of the sample, the measurement was between the bottoms of each side center of the steel plates, and averaged.

The K sample, 48oz, or 0.75psi, was made as an after-thought just to fill a gap in the data. That is probably a common load recommended for using blocks/bricks when laminating a wing with weights.

Perhaps the attached pics will show what was done a little better. So, the following are pics of the test frame, load testing of the 2" x 2" x 3" samples, and the plotted results. I will follow with a post of some testing done of a 2" x 2" x 4" sample, where a curve is cut a 1/2" from each end, to see what pressure it takes to bend the balsa sheet to the tightest radius expected in the build of the 40%Radiowave Extra 300CS.

Now for the testing done of a 2" x 2" x 4" sample, where a curve is cut at 1/2" in from each end, to see what pressure it takes to bend the balsa sheet to the tightest radius expected in the build of the 40%Radiowave Extra 300CS.

The least radius curvature is at the top front of the rudder of the 300cs, and it appears to be about 3". The same sample was used for 3 different directions of the grain of the balsa sheeting top and bottom. No glue was used. I wanted to see what pressure it took to close gaps.

The first sampling was done with the grain running front to back, Sides 1 to 3. That way the weak bending was in the direction of the curvature. It did not take much weight to close the gaps. The steel plate weighs 4.5oz, so the total load to close the gaps was about 8.5oz, or about 0.125psi. However, the previous testing indicated that there could be a small amount of expansion from the glue up to about 0.75psi to 1.0psi.

In the second sample the grain of the balsa sheeting was run side to side, Sides 2 to 4. This put the strong axis bending of the balsa in the direction of curvature. This required a large amount of pressure load to close the gaps. It appeared that 160oz, or 2.5psi, did not quite do it. I was a little concerned that the balsa center and edges would get deformed, so I stopped there.

The third sampling was done with the grain running diagonally at 45 degrees. This required less load, 120oz, or 1.875psi, to get to about the same closure as the grain running side to side.

I did not go any further in the angle of the grain. Perhaps I could try to find a shallow angle to the axis, front to back, that would bring the pressure down to where it is about 0.75psi to 1.0psi. Then it could be assured that the gaps would be closed and there would be little, or no, expansion from the glue. For now I think I will run the grain of the balsa parallel to the leading edge of the rudder. It is probably not an issue with the wings, since the curvature is quite a bit less (larger radius) for the wings.

Yeh... In my yute, in the military, a friend had one just like it. Saw this and the Chevy on sale at the opening of a local Hobby Lobby. So, I decided to make a interior design feature wall in my recently acquired home shop. Another friend from high school had a '57 Chev just like that, same color. He liked to show people how the gas gage would dip toward empty as he accelerated from a standstill. Of course, he was not sucking in that much fuel, it was just from the fuel rocking back in the tank from the acceleration.

That is a very good test Wingwall. That data is very clear, over 3 psi (6 Hg) the foam distorts.

Thanks for taking the time to put this together.
