Ok I don’t know exactly where this would go so I’m gonna leave it here. Ok, my question relates to as you know of course oil streaks. I saw a deal a while back on some website showing how to make a realistic oil streak. I was hoping someone in here would know how to do this or know of a good link for this technique.
Thanks guys and gals.

I usually take a fine point brush with a dark, thick wash and streak it on. Then, I’ll dab it lightly with a damp paper towel to smear and lighten the streak. Here’s an example…

Havent tried it yet but I recently read about a technique for this using Linseed Oil. Said it helps give that bit of sheen oil and gas can leave.
I’d imagine you can just use some artist’s oils and some turpenoid. Just take a little dab of oil and really thin it out with the turp. When it dries, it retains it’s gritty, oily appearance, so it looks like fresh fluid.
If the drip is straight down, just let gravity do it’s thing. It will naturally follow the correct contours. If you want the stain to look like it is wind blown, dab it on and pull it straight back with a stiff bristled brush. It will be heavier at the source and naturally feather out.
Just practice on some scrap styrene to develop a technique.

I thin black oil paint with paint thinner and used a small drop where a leak would originate, then blown it across the surface with a straw in the same direction that the wind would on the real deal. (I’m assuming you’re doing this on a aircraft.) The best part is that if you don’t like it, you can wipe it off with some thinner and start over as much as a day later.
washes made with gloss black look good since they have a tiny bit of shine to it but you can do then with just about anything. Remember the stain will look different depending where it is and when it forms. Leaking when the planes sits on the ground will be influenced by gravity. When flying, is it in the air stream or protected. Even if in the air stream, being thin and right on the skin it will be mostly in what is known as the boundary layer. This is a layer of air right at the skin surface that moves much slower than air even just a tiny bit above the skin. That is why the pitot tube under the wing of a P-51 or Spitfire for example is extended down away form the wing into even air flow. Because of this the oil streak can still be somewhat uneven.
I will put a drop of wash at a starting point and take a can of compressed air like used to blow off keyboards etc and with low pressure blow the streak back and let it take its own course.
EDIT. hannaman got his post in while I was typing. His pic is a great illustration of the blowing technique. Nicely done.
Awesome! I’ve been trying to figure out how to do exactly that same thing. Thanks! [bow]
Glad that this help, Scott!
Thanks, Marc.
I’m going to give that a try on my Hasegawa 1/32 Bf109G-14 flown by Erich Hartmann (winter whitewash scheme) for the Axis Aces GB. The oil stains will look great on it! [:)]
Check out the oil streaks on newoldguy’s 190 inthe the Aircraft section.
Better do a test by putting some Linseed oil on something in your modelling area, and see if you like the smell. It is used as a corrosion preventative in aircraft steel tubing, and has a persistent odor, and almost never dries. Maybe it can be thinned a lot and work OK.
That sounds like a good idea. I’ve been trying to think of some wayto do some minor streaking on my 1/32 Academy F-16 - Thanks wing_nut[:D]
I realize you boys are talkin winged thingys, but here is someting for consideration-- I made these fuel oil stains on these external tanks with ‘future’ straight out of the bottle,faded in with 91% isopropyl alchohol-- might have a place in aircraft also–they look nice and wet around the filler cap-- just a thought-- tread[:D]
Nice trick Treadwell, I’ll give that a try on my Italeri PzKpfw. IVF2 [:)]
Sorry it has takin me so long to reply back, I don’t have internet right now. Thank you fellas for helping me out. I will make sure to try the straw trick, and Treadwell that is a good idea I might just try that with my next model. Thanks again guys
Happy Landings,
Brett
Good call, Tread.
That would even work on some aircraft drop tanks.
I just love that you guys share you knowledge. Just by read the posts I’ve learned a ton! The Corsair and 190 look great! I have never weathered anything, never knew how till now.

Here are a few pics of some oil stains I tokkk last weekend with this thread in mind…
The stains are not always straight back. An aircraft spends the majority f time sitting on the ground, even in war.
Hurricane radiator
wing root and just behind engine cowl of P-47
I love the waythe oil id dripping onthe strut of the PBY. Almost makes me wanna build one just to do that.
Thanks for the pics, I saved them for future ref.
