The New THR Standard

THR Developments is proud to announce our partnership with Wholesale Paint Group and Surventis Coatings, bringing Glasurit premium automotive paints to every THR build.

For us, building exceptional vehicles is about more than the final result — it’s about the products, processes and people behind every detail.

With Glasurit premium paint technology, our builds now benefit from a finish engineered for outstanding colour, depth, durability and consistency.

From the foundation to the final finish, we’re raising the standard.
