Seventies Guy, also known as @that70sguy, is a modeling and diorama-building brand centered on hands-on projects, practical techniques, and retro-inspired creations. Its website shares build journals, stories, weathering tutorials, and gear recommendations drawn from real work at the bench. Featured projects include detailed 1:24-scale dioramas, such as a completed Mad Max garage and a Starsky & Hutch tribute build, alongside custom hot rods and retro mancave projects. Visitors can follow the builds and watch cinematic project videos and tutorials on the brand’s YouTube channel.

The site also offers a free Toolbox of modeling calculators and utilities, with no sign-up required. Available tools include a scale converter, tire and stance calculator, paint ratio calculator, brick grid generator, LED resistor calculator, and material weight calculator. These resources support common planning and build tasks for modelers. Seventies Guy also shares product links through affiliate partnerships, including Amazon; the site states that purchases through those links do not cost visitors extra.
