29:30 - Diesel weathering 2: B&M GP38-2, part 1 (2016)

Mike Confalone kicks off diesel weathering project 2, a moderately weathered blue Boston & Maine GP38-2. Mike reviews a prototype photo and then starts with the roof, weathering it almost entirely with PanPastels. In fact, Mike decides to do the entire loco with PanPastels and avoid using oils as much as possible to keep with the moderately weathered theme of this particular locomotive. Part one of two. Click here to watch part 2.

Another nice episode. I was looking forward to an episode with just panpastels. I have experimented with them myself and find that with a bit of patience, and a variety of brushes, great results can be had, as Mike proves here.  Keep it up!

Interesting about adding the white to the Dullcoat to achieve the faded look. Do you know the ratio? Also on a side note...the weathering you typically see on an EMD on the side sill near the front of the cab is Battery Acid from the large batteries beneath the walkway. Sometimes the acid will even drip down on the front brake cylinder or truck side frame making a rusty look. I'm looking forward to part two of this video as I have two GMTX GP38 units that are a similar blue. 


A couple of questions: I model B&O and Western Maryland, dark blue and black respectfully. To fade the very dark colors do I still mix white with the dullcoat or is some other color such as light gray or possibly is some other shading a better choice? Like a previous comment, it would be helpful to know the ratio of color to dullcoat. When it comes to the Pan pastels, to get the desired effects on dark colors should I use shades such as you have employed or consider lighter shades in the same tones?

I enjoy the weathering series and look forward to trying some weathering. Mike is a natural teacher who both instructs and encourages viewers to give weathering a try. Thanks - Ed

Awesome, as usual! :)

Mike, you are trully an inspiration! Best regards from your biggest fan in Portugal!

Can fingerprints be avoided by wearing disposable surgical gloves while weathering and/or spraying Dullcote?


Can fingerprints be avoided by wearing disposable surgical gloves while weathering and/or spraying Dullcote?

The answer would be: yes, somewhat.

Surgical gloves often come with a bit of talc on them so they don't stick together, and that will also keep your fingers from sticking to the model as readily. That said, it's also likely using the gloves will replace the ridged look of bare finger prints with a general round smudge instead. So gloves won't be a cure-all, but they probably will help.

Thank you.


love the weathering series it has inspired me to start weathering cars on my railroad , it really helps to see it done before I try it myself on projects like this , on a note about the dullcoat with paint for fading what paint do you use and how much it looks like a great effect , thanks

Great results just going step by step with reasonably simple techniques. I wish you'd done the series 20years ago. One question, how do you handle the windows during Dullcoting? Mask, remove, clean afterwards...or just don't worry about them?

We believe early on Mike mentioned in quick passing that he masks the windows with painters tape before dullcoting.

Mike. I've just finished watching all your weathering videos. You make it look so easy. It has inspired me to go out and get some Pan Pastels and oils and give it a go. I see in a previous post that you mask your windows with painters tape before applying Dullcote. Do you also mask the wheels somehow? I assume you use an airbrush, but do you think using a rattle can of Dullcote would work as well? 

I'm looking forward to the next video in the locomotive weathering series.

Mike;  Great video on pan pastel weathering.  When using pan pastels, aren't you afraid of getting the dust from these into your working gears and electronics inside the shell?  I mean it looked like you just brushed over the top of the fans, exhausts and grills that were open?  Do you do your DCC installs and lighting before or after the weathering?

Thanks and I really enjoy your videos,  Cameron White
