I just started watching Donn Yost and from the 20 videos and a DVD that I've watched so far the only thing similar here is the 1 to 1 ratio of Testors enamel and lacquer thinner. The fat paint coat is a twist on the Yost method...Yost is doing many thin mist coats allowing the paint to build up slowly. He has a Patreon with 263 posts and MANY of those are 30-40 minute videos where he covers everything about model cars. Well worth the $4 https://www.patreon.com/ScaleModelTechniques/
