Dominion Sure Seal Paint Primer
Dominion Sure Seal Paint Primers: Professional-Grade Surface Prep
When it comes to automotive refinishing, the foundation of a lasting paint job is the primer underneath. Dominion Sure Seal has been engineering automotive surface-prep solutions since 1972, and their paint primer lineup reflects decades of real-world bodyshop experience. Whether you're a professional technician chasing faster cycle times or a dedicated DIYer tackling a panel repair, Dominion Sure Seal offers a primer formula designed for exactly your situation.
A Primer Line Built for Every Substrate
One of the defining strengths of Dominion Sure Seal's primer portfolio is its versatility across surfaces. Their primers are excellent for use over bare metal, aluminum, previously painted surfaces, polyester body filler, plastics, and SMC/fiberglass substrates — and they are quick to dry, easy to sand, and offer great film build and flexibility.
At the heart of the lineup is the 3-in-1 Primer series (available in grey, black, and white). A revolutionary product designed to prime and fill in a single step on plastic, steel, and aluminum surfaces, it is sandable in as little as 15 minutes and paintable in as little as 30 minutes — a genuine advantage in any shop environment where throughput matters.
Etch Primers for Bare Metal and Aluminum
For repairs that expose bare metal or aluminum, Dominion Sure Seal's acid etch primer range provides critical corrosion protection at the substrate level. Their Super Acid Etch Primer (SEPA) is their most aggressive etching formula: it offers superior corrosion protection while promoting adhesion of additional primers, sealers, or topcoats, and is recommended for aluminum, bare metal, and seams before sealant is applied. It is fast drying, prevents steel from rusting, and can be top-coated in as little as 10 minutes.
For mixed-surface repairs where both primed and bare-metal areas exist, the One Step Self-Etch Primer (SEP/SEP1) offers a more forgiving solution. It can be directly top-coated and applied over mixed surfaces such as primer, filler, and metal.
Adhesion Promotion for Plastics
Modern vehicles use plastics and TPO (thermoplastic olefin) extensively for bumpers and trim panels — surfaces that demand specialized primer chemistry. Dominion Sure Seal's Adhesion Promoter Spray is a powerful primer that enhances paint adhesion on a variety of surfaces including plastic, chrome, and metal, and works effectively as a preparatory coat for spray paint, clear coat, and car paint applications. Formulated with a quick-drying agent, it prepares surfaces in minutes, ensuring a rust-resistant, even application that lasts.
Trusted by Body Shops, Built for DIY Too
Established in 1972, Dominion Sure Seal is a leading manufacturer of sealants, protective coatings, and adhesives primarily for the automotive paint, body, and equipment industry. Their products are available in over 2,600 stores across Canada and have reached international markets since 1985. That depth of professional distribution speaks to the trust collision repair specialists place in the brand. Dominion Sure Seal offers a complete line of primers and clear coats — covering weld-through, etching, high-build, 3-in-1, and 2K sealer surfacers — making it straightforward to source exactly the right product for any repair stage.
