Hi guys, hope everybody has been doing well out there! I’m getting ready to start on my first weathering project and I had a couple of questions that for some reason weren’t answered on some of the tutorials that I’ve been looking at.  I know that there are a lot of different ways that people weather and that none of them is wrong, but what I am asking specifically relates to the way that I’m doing it with acrylic paints, Pastels and weathering powders.

1. after every layer of paint or chalk, do I have to add clear coat?

2. When adding shocks or powders over the paint, do I add them while the paint is still wet?

3. What would you guys recommend when it comes to mixing the acrylic paint and water(ie what ratio) or do I just add a little bit of water at a time until I get the consistency that I’m looking for?

Like I said this is my first time weathering and I want to do a good job on the item of less value that I have so that way I can perfect my technique. That being said any tips you guys can give me would be very much appreciated!



i’ve also attached a photo of the item that I’m going to be weathering. This is an old weaver tank car that’s been pretty beaten up from its previous owner and I figured rather than throw it away I could actually use it for a guinea pig so to speak for learning how to weather so that I could perfect my technique before moving onto some of the cars of value that I do wanna weather.  I’m turning this car into a cool DIY project that I think will turn out very well and once I have it completed I will post some photos here on the forum.

Thanks,

Drew

1. after every layer of paint or chalk, do I have to add clear coat?

Paint, probably not. Chalk, probably. The chalk will continue to move around until you fix it in place. I'm not suggesting that you use 1 color, spray it, use the next color, spray it, and so on.... but You'll get to a point where you'll want to give it a spray coat and see what you end up with before continuing.

With acrylic paint, unless your next planned step involves something that will remove the paint (like something diluted with alcohol), its pretty well stuck on when dry.

2. When adding shocks or powders over the paint, do I add them while the paint is still wet?

Generally, let it dry. There is a technique where you mix the chalk INTO the paint and then apply it. But applying it into the paint after the paint is on there just sounds like a recipe for a mess.

3. What would you guys recommend when it comes to mixing the acrylic paint and water(ie what ratio) or do I just add a little bit of water at a time until I get the consistency that I’m looking for?

The more water, the lighter it'll end up being. There's no golden rule here. You want the paint to run, but how much water will govern the final effect. One word of caution... using straight water will cause the paint to pool at the bottom edges of things. When it dries, it'll leave a "watermark" of paint. Put a little alcohol in it to break up the surface tension, or be prepared to wick the bottom of the panel with a paper towel to prevent that from happening.



Theres many ways to do it. if you're messing with a "throwaway" car, then there's no wrong way to learn. Just make sure you work top to bottom... it never rains up.

As far as weathering rolling stock and locos I have limited experience. When I was in semi scale I tried fixing chalk with dull coat and that did not work for me probably because I did not do it correctly. But may I suggest trying some techniques on some different painted scrap plastic to get an idea of the different results. Just a thought. Good luck on your weathering.

I've only weathered once.  I used all powders except for the coupler and the truck springs that I painted rust color.  I did all of the powder first and blended.  Then after powder and paint was applied did I spray with a dull clear coat.

When you spray, make sure you hold the can far away enough that you don't blow the powder off the car.

Have Fun!
