Built On Trust


Mark Supply, Inc. is a family-owned and operated leader in automotive reconditioning and detailing supplies, proudly serving Central and Southwest Florida for over 30 years. Founded in Venice, Florida, we’ve built our reputation on delivering premium products, outstanding customer service, and the knowledge to help professionals get the job done right.

We’re your one-stop shop for everything from detailing chemicals and accessories to service and body shop supplies, sales and promotional items, and national brands like 3M, Au-Ve-Co, Rupes, Flex, and DeWalt.

Unlike traditional distributors, Mark Supply brings the warehouse to you. Our dedicated route drivers deliver, stock, and restock products weekly — ensuring shops, dealerships, and service centers always have what they need. Customers can also visit our Venice showroom or our Sarasota/Bradenton showroom, which features TRT University — our professional training center offering hands-on detailing classes for beginners and industry experts alike.

Our exclusive brand, TRT – The Royal Treatment, represents the highest standards in quality, service, and customer satisfaction. We provide in-house and field product testing, along with hands-on training and education, so every customer feels confident and capable using our products.

At Mark Supply, we don’t just sell supplies — we partner with professionals who expect reliability, expertise, and care. Whether you’re running a dealership, detail shop, or service center, our goal is simple:

To deliver The Royal Treatment in every product, every visit, and every customer interaction.
