P38L Top Speed

[Ack-Ack]

No, you're plenty fast enough already. 

Only after I eat Mexican food and use the gas as added thrust.  Hey, maybe we can get that modeled?

Increase an unpainted P38L's top speed by 8 MPH due to a reduction in skin drag and therefore the drag coefficient

Actually the speed could be slightly higher since the area of the P38 is larger than the implied P51B test plane.

The unpainted weight reduction is a wash since I found suggestions that the frame on the L was beefed up to carry larger bombs than the "J" although I can't confirm that.

You misread the article. Only polished aircraft, regardless of paint, show reduced drag from skin friction. You are also assuming that top speeds in game are from unpolished aircraft.

Shh, Shida. If we can convince HTC that he's right we can claim the Ki-84 and Ki-61 bare metal skins deserve a decent speed bump too. 

I think there's too much speed and not enough fight in the MA already

..Fair point.

Then that means the bare metal P-38J I fly should also get a speed bump.

Default skin model.

Anybody notice that most all of the reno racers are fully painted?

Indeed, no doubt with perfectly smoothed paint jobs in good condition and waxed to perfection. Probably easier to keep bare metal slick under service conditions. Still no to the OP's wish though.

The mil thickness and weight per gallon are way less than WW2.  I think it is like 5 pounds vs 30 pounds.

An Air Force test showed a painted, sanded and waxed B17 flies faster than a plain, unpainted, unpolished plane.

Dago Red and Voodoo had up to 30 gallons of bondo on them and one had 11 layers of different paint jobs.
