Various rusted and corroded metal

[kmdl1066]

GW have a neat little section on getting various rust and corroded metal effects. I particularly like the suggestion of supergluing fine sand to create areas of corrosion.

Painting Metal

So now my question to the knowledgeable is this: how do you go about pock marking a smooth surface (for metals and plastics) so that you can use all the ink & drybrush techniques they do? The bigger holes I can understand (pin vice, knife etc) but how do you get the hail-damage type effect?

I think it\'s the door they used - it already has all those dents in the cast. You could probably create them with some kind of rotary tool or by applying a thin layer of green stuff (let it harden a bit) and then pressing a lot of dents into it.

I have used a knife and a pair of dividers. Randomly pick, pluck and scratch.

I have found adding baking soda to the paint creates a better scale for the rust.Sand would be too large.

YOU could also try placing a piece of very coarse sandpaper on the item and tap it with a small hammer to cause the indents. That could work quite nicely on green stuff as well.

I have mentioned it before and I\'ll add it here I recently took my wife to a doll\'s house exhibition at Birmingham NEC and there I came upon a product called real rust that I am currently experimenting with and have to say that the firs tests that I have done are excellent.
It is a three part medium the first two parts are mixed together to form a black paste the consistency of which can be altered to taste. The third part is the rusting agent which is applied over the blackened areas when dry and again the more that is added the heavier the relief and like I said it is very very realistic looking.

On plastics, you can add liquid polystyrene to areas with drilled holes to roughen the surrounding areas.

ive always wanted to pick up some of that real rust stuff. but i cant seem to find it anywhere.
for big holes you could use a dremel tool...but very carefully.

Now how brilliant is that?!? :idea:

Like Trevor\'s suggestion of using plastic glue to melt the surface of the plastic to roughen the surface, spreading superglue onto metal can also create a finely roughed surface. Putting a drop on, and then very quickly smearing with your finger it will do the job. Sandpaper will work too, but my fingers are always handy and available.
