I’m planning to dig in to salt weathering, and some pepper, for the first time on my current project. My plan is to have some areas look to be worn down to bare metal and some areas only chipped or worn to another paint level, sort of down to a primer coat. Am I going to run into trouble with that or are there any precautions I should take, since I’m going through a couple of coats of paint on the weathering.
Oh, and does anybody have any ideas on how to induce a clear coat failure, in random spots, in model gloss coats. Any ideas on product and method are welcome.
You’re going to want to have a very solid NMF as a primer.
Salt applied sparingly will help with the chipping effect…heavy for the well worn areas. Using various types of salt is another method…large crystals for heavy chips and table salt for finer ones. Experimentation is key to learning this method.
I’ve also used dilluted white glue too…I just washed or peeled it away with my fingers.
I like to use a polishing stick to induce similar effects in paint…scuffs, scratches and faded worn thru effects call all be added with a polishing stick and a light touch. No salt needed but can be used in conjunction with. The polishing stick will also ease those edges to feather them.
I’ve done salt weathering on multiple layers and it works exactly the same as doing it on one layer.
If I recall, I used a base layer of alclad aluminium, put down some salt, sprayed the next coat, put down more salt and then sprayed the top layer. After everything was dry, I scraped off the salt to reveal the layers below. I combined it with other weathering techniques to get the final effect;
I just used a toothpick to scrape it off. The only I made sure to do was to scrape it off in the direction of airflow, so that the weathering made sense.
