Not sure what happened
Posted by Anonymous on Monday, November 10, 2003 3:22 PM
I was doing the salt weathering technique that I read about a few issues ago and although I like the way it helped with the paint chips I am not sure I like what it did with the paint. I am assuming that everyone has seen the article.

Okay I did this on a F4U and also on a Zero. On the F4U I airbrushed with Testors Model Master enamels and on the Zero I airbrushed Tamiya acrylics. In the areas around the salt the paint went on with a lighter color, almost like water spots. No matter how many times I sprayed it again the paint would not get any darker.

I am assuming that there was some reaction between the paint and either: the water (tap) I used to apply the salt or a reaction with the salt itself. The reason that it say that the reaction was between one of these and not the paint itself or the thinner is because one was painted with enamels thinned with paint thinner and the other was acrylic thinned with IPA. Anyone else have these results?

So with some extra weathering I was able to cover up the uneven paint using artists water colors and pastels but I sure would like to know what actually caused the paint problems.

How does the "salt " technique actually works?

What I did was airbrush the model with aluminum. After that dried I took a wet paint bursh and applied water (basically small water drops). I then poured salt where the water was. I used a paintbrush to move the salt into the postition that I wanted, leading edge, walkways, etc. The salt was wet so it was easy to move around. When the salt had dried I airbrushed the top color on. After that had dried I then picked off the salt which exposed the aluminum. This gave the paint a chipped appearance. You can also grind the salt into the paint and this will give it a scuffed appearance. I think it works pretty well I am just curious as to what caused the "water spots" in the paint.
