I have read about chipping with salt, and tried it once... not very successfull.
What size should the grains be?

In my case, I first painted the AFV dark gray. Then applied water to the areas that should be chipped and then salted the areas.
Then I painted it with a lighter shade of gray.

I got the chipped paint effect, but it seemed like the salt extracted water from the tamiya acryllics paint. The result was a very light gray circle around the chpped area...
Could it be that I did not use "real" salt but a healty substitue for salt we in Norway call "Seltin"?

I have also tried the salt technique. It works ok, but there is a better method, at least I think.

Paint your model with the base coat, then with a torn up Scotch Brite pad (or equivalant) apply either Humbrol Maskol or Vallejo Clear mask with the torn up pad in the chipped areas you want. Then apply your top coat of paint. Once you paint has cured all you do is rub your finger over the masked areas and the mask will come up leaving the base coat showing through. Here are a couple pictures of the techniques results.




Hope this helps.

Cheers,
Ryan

I'm not familiar with Scotch Brite. Is that a kind of microfiber cloth?

Hi Henrik,

I had a similar problem when I tried the Salt method with Tamiya Acrylics. I have not tried it since (as I prefer Maskol) but maybe a try with Enamals might work?

Cheers
Henk

Microfiber I believe is the same thing. It's the pads you use to scrub kitchen counters if that helps any?????

For the salt method use a large crystal salt.Kosher salt is one.I believe sea salt would be another. Could also buy salt from a pet store..the type used to make fish tank water briny.

Hi mate. Scotchbrite is just a brand name for non stick pan scourers. They are usually green pads about 4 inches by 3 inches, made of a coarse woven fibre. They should only be a few krona, dollar or whatever for a pack of 3 or 4.

I've used the scouring pad method on my desertized italeri T-55 - but slightly different.
First I sprayed the whole thing a sand colour, then used the scouring pad to 'chip' the surfaces using a dark green colour.
If you do it this way round you don't get the chipping near the inside 'edges' (where the tops of the track guards meet the side bulkhead for instance).
Looking at old construction equipment at building sites it seems that scratching and chipping occurs more in exposed areas than in recesses etc.
Hope this helps

The problem with the salt technique you are describing is because you are using acrylic paint...the water/alcohol in the paint mixes with the salt and slightly dissolves it, leaving the white residue.

If you use enamel paints, you won't have the same problem. But enamels are that much more of a pain in the butt.

Sounds like the salt technique is not so good when using Tamiya Acrylics. I'll try using masking and scotch brite instead. Thanks for all the advise.

You guys reply fast....

More importantly, look at period photographs of the equipment you're modeling. Construction equipmnet is treated significantly diifferently than military equipment and is likely a lot older than any World War II combat equipment ever got to be. The oldest tanks in German service would have been barely 6 years old at the end of the war.

I used the salt on Tamiya paints and I too had the whitening of the paint around the salt but I just integrated the effect into my weathering and it acctually looks quite good.

Same here. Below is a photo of a project I have been working on for a while now. You can see the slight discoloration around the paint chip areas. I was able to soften the contrast by applying a wash and dry-brushing the model. I think that discoloration actually added a little bit more realism.

Went to the store today to buy a scotch brite pad. There were quite many to choose from. I came home with this one:




Did I pick the right one?
