Update...
The right (starboard for you rust pickers) wing went into the booth and got Polysprayed, white undercoat of Polytone then Red and White Aerothane...
When I shot the white panels on the wing I also shot the rudder. One more wing to do up from the Polybrush coat and I'll have all the big pieces done.
Polybrush sprayed coats.

Polytone White undercoat.

Aerothane white and red.

While waiting on various things to dry I got the engine hung, finished up the wiring for the starter and got the brakes assembled and bled.

I DID have one setback since the last update...my trusty spray gun I've used for 15 years bit the big one 😡. All I had left was my Iwata detail gun and it's way too small for painting a wing. I ended up getting a cool 3m Accuspray 2.0 gun that has easy-change heads, throw away liners and tops and a built on regulator.! It came with 5 each 1.3, 1.4 and 2.0 nozzles... the 1.4 worked great for the silver and the 1.3 @ 18psi really laid down the Aerothane (which is a real b-atch to shoot) great. I'm still playing with the setup but for $350.00 it's not bad at all.
On to the left/port/other wing tomorrow...

A small disaster...
I shot Red Aerothane on the ailerons, horizontal stabs and elevators.
I then left to get to an appointment.
I got back to the hangar Tuesday morning to discover the high winds we've had blew a vent cover off the rear wall and tore up the rear section of my spray booth. Inside I found lots of FOD in the fresh paint. 🤬🤬🤬
Right now my plan is to just let it dry for a month or so and color sand and buff it out...if I get most of the crap out I'll just call it good. After all; paint on warbirds was never that great...(at least none of my dads stuff).

Ugh, bummer. Seems like sanding out the crud and reshooting red would be no more labor intensive than color sanding and buffing?

Every paint job has those blemishes that irritate the painter to death, but no else seems to notice. Aerothane sets up pretty fast. I'd give it a few weeks and see what washes off. I'll keep my fingers crossed for you.

Left wing is done. Starting to like my new spray gun...🙂

I got tired of screwing around getting the FOD out of my flippers so I removed the covering, re-covered and painted.

Also got about half the trim pieces painted...including some screws for the window trim.

I've got the instrument panel (such as it is) going together and after I double check the fit of the boot cowl I'll get it, the door and the struts shot.
Then final assembly and paperwork...lots of paperwork 😳😳😳.
My wife said if I'm not careful I'm gonna finish this silly thing...

How long does covering a tail surface take?
Actual covering, taping, riveting was a day and a half for all four pieces...
Paint thru red was another week...
Drilling out the old rivets wasn't as bad as I'd envisioned...
A dremal tool with an 1/8" tungsten burr bit popped the tops off the rivets without having to drill them thus not enlarging the existing holes.

I found one of my mufflers internal baffle (firecone) was about to come apart 😡🤬😡.
As I haven't spent any money on airplane stuff yet this year (wife started to worry if I was OK) I decided instead of rebuilding my old muffies I'd spring for new!
I can't wait to hear the low, powerful growl of my C 85 emanating from these...just like a Merlin V-12 at full throttle.

Sort of. 🤗🤗🤗
