How do you make a pice of plastic look like a rusty metal part? i was feeling stupid and i youtubed a method of making rust and tried it on my PG Zaku and im not to sure if it looks right. i need another opinion.24932494

Well if i was you id not try new things on really expensive models. why would you do that? WHY???

That looks pretty darn good to me man. Way better than anything that I could do. I'd believe that to be rust on 1st glance.

One of the first things I always ask myself before I tackle any project is... what's the motive for anything? What's the reason for things to be there?

In your case:
- Are you trying to paint a model to look like it's been de-commissioned? Just sitting there to rust away. How long? How badly?
- What parts should receive the rust? Surely, not EVERY mechanical bit would rust, would they? (rubber housings, etc. wouldn't rust)
- Would that part theoretically be exposed to weathering/rain/acid rain? Would it be covered up by a panel so it wouldn't be affected by weathering naturally?
- Is this planetary rust? or space rust? What and how is the difference?! That would be cool to experiment.

Any model would look 10x better if there was a story behind it. Even as simple as weathering/rust, it could show the viewer where it had gone through to get to that state. You are the artist and storyteller.

Google rusty cars. Look for images of rusty cars in different states. From the initial "bubbling under the paint" to full on gaping holes in panels. Save them as reference. Pick a few selects and try to imitate it with your brush! Have fun!

I would also like to know how to "rust" gundam models

That space rust comment brings up a very good question. But i think in space there is no air so oxidization(rust) is impossible. And on the ship where the mobile suit spends most of its time there is the recycled air so there it can rust. What im going for with my Zaku F is i want it too look like is has been going to fight spending some time in the hangar then going to fight again with not much time for maintenance between fighting.(In space because its an F type) so there would be a lot of rust and burn marks even under the panels where the thrusters burn the armor and mechanical parts heat up and show signs of slight burning and some parts to show shiny metal to look like it has been freshly worn over all i want my Zaku too look like a Veteran but not defeated just worn hard oh and Wiltonican your comment motivated the heck out of me. will you be my friend? lol

in my opinion i don't think i would go with rust as much as just grime and thruster burns as well bare metal scraps.

reason being if you are going for a battle hardened veteran look he is not gonna be a rusty. if you think about military vehicles they don't let there machines get rusty they maintain there machines they may not clean them but when it comes to function you keep your tools in tip top shape.

but the work you did do looks amazing

Nice rusting on your first try =).

I must say that, there are a lot of zaku's that made it to earth which were subject to earth conditions in the anime, so "technically" rusting a gundam is totally legit, as it was also prone to erosion from rain and such.

To answer your first question and RX-78-2's curiosity.
There are quite a few techniques for those of you who want to know how to rust a gundam.
There's the salt + hairspray technique, sponge technique(DC23 uses this one quite a bit and has a youtube video demonstrating this I believe), and even painted on weather rust(used by the armor building modellers)
The most common method so far seems to be the salt + hairspray technique


I have found a few websites for you which I think would be great resources for the future:

Very good resources thank you. and what im going for is as you said a veteran Zaku pilot who has made it from fighting in space to the earth sphere. with little time for maintenance. what i mean is the mechanics working on this Zaku were rarely the same mechs and they didn't really have time to bust rust just fuel the Zaku, fill hydraulics, replace the pneumatics air filters, replace or repair shock absorbers, load ammo, replace the battery on the heat hawk, check every system and mechanical bit, fill oxygen tanks for the life support systems, replace the Radium in the nuclear reactor, im sure MS use nitrogen and liquid oxygen for cooling like aircraft do. i can go on and on. but i think you get the idea there's not much time to bust rust or fill in bullet holes. basically if the Zaku will work without needing to fix it we dont have the time to fix it. but u know how reliable Zakus are.

Well, the MS can come in dirty from battle, get a quick hose down from the repairmen. Where there are battle wounds, most likely the paint would be chipped off. The water coming in contact with the newly exposed metal bits can accelerate the rusting process.

How about the nuts and bolts of the panels and such. I imagine the wrenches torquing them off so many times for service would also wear down the paint. (Corners and edges too) Then rust would come to play there.

gdx9902 has some pretty good reference sites there!

Ah ic, if you were going for that look as in, the zaku has fought in space and just made it to earth sphere, It would kind of depend how long he/she was on earth sphere.
From my understanding rust doesn't occur right away and takes time to build up. So if you were going for Just fought in space and just landed on earth sphere, I would agree with some of what Wiltonican said, such as paint chipping and exposed metal bits, but also some burn marks due to the heat of re-entry into earth's atmosphere, instead of rust.


But if the zaku was on earth longer, then there would be the rust, dirt, exposed metal, chips in paint, burn marks, etc.

One reference I would like to recommend is from an episode of MS igloo which has zaku's on earth sphere for a while but in the middle of zeon's assault on earth sphere.
I believe there are two good episodes with reference, one is with the ogre zaku:
http://quentinlau.blogspot.ca/2008/11/ms-igloo-2-new-trailer.html

The other is the episode with the artillery tank:

http://natakon.blog.so-net.ne.jp/2010-03-31

The zaku's depicted in there were the ones who fought in space and were dropped into earthsphere. I hope the details are sufficient enough for you to get an idea. And I hope I got the right idea you were going for.

I hope this helps.

I need a air brush. its too bad there so expensive. Do any of you know how to make a rusty streak line that fades away like a rusty bolt head has that run off of rust? know what i mean?

Also has any one used dry pigments? that powder stuff is apparently very good for rusting models.

The rusty streak line is done mostly by fine brush or toothpick from what I have seen.
I believe one of the resources I posted before may have an example of that. If not, check out www.armorama.com, they have lots of rust streaking techniques.

As for dry pigments I have used it. I just use either tamiya weather kit or doc's weathering powder. They must be applied on a flat coat surface since it is quite rough so they stick better. also they are very very loose and you can literally breathe the powders off if you are not careful. I have used it on my char zaku there to simulate some space dust accumulating over the missions.

To apply weathering powders and dry pigments, you use a very soft bristle brush or a dry sponge brush(like the ones the ladies use for make up) and just dab the surface you want to have the pigments stick to.

Thanks dude. and also good job on both the Char's Zaku and the Musha Gundam

Don't know how far you've gotten with your weathering experiments. But, I came across a pretty cool (non-Gundam related) painted model that has great rust effects.

Oh, it's a custom modded vinyl figure...

As far as weathering is concerned I have 2 types of the Tamiya Weathering kits and they work amazingly well. Each kit has 3 types and a 2 sided makeup brush to apply it with. From there you can rub it in how you like before top coating. Highly recommend looking into them because of how easy it is to get good weathering results.

After using them for a while I'm considering hopping into a CVS & looking for some weathering esque eye shadow makeup to mess around with haha
