30 mph loss? Yep, that's significant. I recall a post awhile back, here on VAF IIRC, about the performance difference between flush riveting and round head rivets. Seems they glued split peas on the exterior of a Spitfire to simulate domed rivets and suffered a 25 mph loss.
OTH, a flat finish can look really cool.

I actually already painted it in Sherwin Williams MIL-PRF-85285E Lusterless (Flat). It’s essentially flat Jetglo that complies with a military specification. It’s tough as nails. I accidentally dropped my biggest flat blade screwdriver on it and not a scratch. However…. The airplane is 30 MPH slower than before I painted it. My airspeed and GPS indicate the same with no wind. Compression is good. I was just wondering if anyone had painted theirs flat and if their performance suffered. I love the color and finish but 30mph is a bunch.
Wanted to fly instead of paint. This is VeriPrime. Soon I will paint it but will go with grey military instead and not go completely flat. Paint adds weight....
Bugs and oil etc can be an issue but then it looks more military.
Veriprime does nothing to prevent corrosion. Also, when it comes time to paint, paint stripper will not take it off. MEK and scotchbrite will though.
I’ve been down the veriprime road many times.
