Few things add realism to a model railroad light good weathering. Here are some techniques I use when weathering freight cars for my N scale layout. These techniques can be use in any scale. I demonstrate them on an Atlas covered hopper.
I follow you on youtube I log in with Google and can not leave you a thumbs up or comment. I saw the article you posted and I think anyone starting out weathering it is a very good article.
Thanks for your comment here. You should be able to do that on YouTube if you are ligged into Google, but I'm glad you left one here. Thanks. Sent from my SM-G900V using Tapatalk
