Quick tips: Exhaust stains 2.0 - scale model weathering tutorial

In this video I am going to show you my updated technique on piston engined aircraft exhaust stains application. This weathering technique will add a few more layers of complexity to our builds so it is definitely worth giving a try.

G'day M, Very logical exhaust 'weathering'. A lot of people don't realise that, during wartime operations, WW2 aircraft were allowed to get into an awful state because of little to zero livery maintenance. Painting the surfaces, apart from vital aircraft ID numbers etc., were not on the ground or deck crews' agendas.
The degradation of paint jobs were even worse on carrier borne aircraft due to the effects of salty, sea water spray. The fading and wear of USN's blues, say on WW2 Corsairs, was particularly bad. Sometimes almost fading and wearing back to the base primer or metal.
As prop aircraft gave way to jets, this kind of weathering and exhaust markings were not as bad.
It was also calculated that there were real fuel savings if jet aircraft surfaces were kept as smooth as possible. This can also be seen in the increased amount of bare metal jets where the added weight of paint was not always worth the extra fuel needed to carry several coats of paint around on the aircraft. (Given that most camo schemes on WW2 aircraft were absolutely useless; but that's another topic.)
When I began reading about the weight of several coats of paint on large aircraft I was amazed. There are real fuel savings to be had just by polishing the bare metal as smooth as possible and then applying only one or two coats of clear 'sealing paint'.
Many B-17 squadrons ceased carrying all olive drab or total paint schemes towards the end of the war. Only a tiny handful of B-29s had all over paint jobs. It was such a large aircraft that it made sense not to weigh them down with paint.
Of course, aircraft like C-130 Hercules and Orion aircraft can be made to look a lot 'cleaner' by their areas of black matt paint put over areas were engine exhausts are at their worst.
These days airlines go to great care to paint up their aircraft with super smooth yet thin coats of, usually, white paint to retain smooth aerodynamic surfaces that, again, reduce fuel consumption. The savings per aircraft are, indeed, small but when taken over airline fleets of hundreds of planes, using as little paint as possible has huge cost saving on how much paint an airline has to buy each year.
Thanks, again, for another quick, informative and helpful video! Cheers, Bill H.

Very realistic and not to labor intensive. Thank you.

Gives a fantastic result😊
I like how you explain why you are painting certain lines .
Thanks again,

Thanks you make things sound so easy for all of us to try and see what are the results.

Thanks. :) Just what I needed. Will paint exhaust stains next weekend and wanted to try to airbrush them for the first time.

[@MMScaleModels]

It is worth the effort IMO.

Great video. May I ask what airbrush are you using? Is this Iwata HP-BH ? If yes what’s your opinion on it? I’m in the market for decent airbrush and can’t really decide which one to choose. Either H&S CR Plus or Iwata. Any advice would appreciated

[@MMScaleModels]

Thanks, I use an inexpensive Chinese airbrush - 0.2 Fengda BD-208. Have never used any of the well known brands so cannot comment on them.

Thumb print?

Yeah, one more reminder that gloves are a must. Appears that hairspray is not holding well on oils... fingerprint chipping may be a legit technique 😄

Mmm, don't recall. Something low, like 0.7 - 0.8 bar.
