Topcoat selected firewall and fuselage components

All components and surfaces forward of the firewall primed with EkoPoxy. Ekocrylic battlehsip grey was used for the topcoat. Devilbis ProLite gun, 1.3mm nozzle, TE10 head, 26 psi at the gun regulator, gun cheater valve removed, paint mixed in 4:1:0.88 Part A, Part B, water ratio with viscosity verified to be 26 seconds with AES 47399 Ford #4 cup. Paint is allowed to cure for first 12 hours in 20 Celsius environment, after briefly being outdoors for a few minutes in 12-14 Celsius environment during the actual spray (maybe the latter is a bit of a problem). The gun fan control is opened up one turn, paint flow opened 1/2 turn for 2 or 3 fog coats, opened to 3/4-1 turn for the wet coat. I am getting better at filling the "dusty" fog coats with the final wet coat.

Maybe the slightly cooler temperature during the actual spray is a problem. I sprayed some centre fuselage parts in the more temp-controlled environment and achieved a slightly better result.

Because I am using a wider fan, in order to maintain gun pressure I am blowing through more paint. For small components this leads to waste. Consequently I think I will need to purchase another can. This will not be such a problem for the exterior surfaces.

The mottling/orange peel is still evident, but less bad, and more predictable. The reflected flash and lights are making it much more noticeable than in practise. These parts are still largely out of sight. At the same time I am not blowing though all the paint without making useful progress. I still want to improve the result, but I am getting closed to feel like spraying the fuselage bulkhead etc. I don't care about getting a perfect mirror finish to the paint. If I can get a subtle but consistent "hammertone" quality I will be happy.
