Dupli Color Chrysler Black Pearl. Looks even better in real life. The iPhone struggled getting the white balance right. It has a very deep look to it and has a ton of sparkle in the light.

I have pretty much switched to Dupli Color car paints. They work very well and I can prime, sand spray and top coat back to back about 10-30 minutes apart without the paint screwing up or running/sagging. Their build up primer and sealer are awesome for rattle cans. When you sand, dust is actually made instead of little gum ball of paint.

Jarod,

Question: Is the Duplicolor a "real" metallic meaning fine reflective metal in the pigment? Reason I asked is I had a Rustoleum rattle can metallic painted rocket
that was totally opaque to the 70cm/430Mhz Rf of a Beeline GPS tracker. In fact I know for certain it's opaque to Rf in that I had two rockets painted that
way and flew both the same day. One I found, one had a ballistic deployment of the main after apogee failure. The one that was found we had a visual on the other no. No Rf was received after the button was pushed in either rocket.

That's what I think of when I see metallic painted rockets. If it's a high flier what's the chances it will be tracked reliably?

Yes, the attenuation is dependent on power output and frequency. The one rocket recovered above I went through the motions of downloading the .kml track file
off the Beeline GPS expecting nothing. To my surprise, the GPS kept a 7 to 11 satellite lock throughout the flight to 10k'. Shows the GPS could receive the satellite signals through the paint though the Rf couldn't get out. Not only that, I had the Beeline set the stop recording once is got to the end of the memory. I didn't expect to turn it off until I got home. The .kml tracking file even showed where we went to a local pizza place after the launch. The GPS must have been facing up and receiving signals through my trunk!

Due to that reason, I won't paint a tracker bay with metallic paints. Now if another person says they've painted a few rockets with X,Y,Z metallic paint and
they've had no problem tracking with "Type X" Rf tracker I would consider it. It would be demoralizing to spend a lot of time and work on a rocket only to find
out your tracking setup only has a 1/2 block range on the ground. Not a good ide to fly under those circumstances.

BTW, absolutely beautiful results Jarod. I'm envious. Kurt Savegnago

Hi Kurt,

I honestly don't know if this is a "true metallic" paint. It is listed at pearl. I don't see any mention of it being metallic. I do know that some "metallic" paints do not use real metal flakes. Without contacting Dupli, it would be a just a case. In my case. The nose cone is for a Mega Der Red Max, which might go about 1000' or just a bit higher, but clearly trackable without low cloud cover. I have read other posts regarding tracking units inside of rockets having issues with metallic paint, so if I ever start adding that kind of tech to my rockets, I will take that advice and paint the entire system or at least the AV bay with plain paint so as not to interfere with the electronics.
