Klean-Strip Adhesion Promoter

Klean-Strip Adhesion Promoters: The Bulldog Standard for Paint That Sticks

When a paint job fails, the culprit is almost always surface prep — specifically, a lack of proper adhesion. Klean-Strip has built its reputation as a leader in automotive surface chemistry, and nowhere is that expertise more evident than in its line of adhesion promoters. Developed under the iconic Bulldog® name, these products are the go-to choice for professional body shops and serious DIYers who can't afford a paint job that peels.

The Bulldog® Adhesion Promoter Lineup

The flagship Bulldog® Adhesion Promoter is engineered to promote paint adhesion to all automotive surfaces, including the notoriously difficult "problem plastics" found on modern bumper covers, trim panels, and mirror housings. It works equally well on flexible or rigid plastics, fiberglass, aluminum, glass, chrome, vinyl, galvanized metal, and previously painted surfaces — making it one of the most versatile adhesion primers on the market.

One of Bulldog's most practical advantages is its tie-coat technology: it acts as a bonding layer that allows several different substrates to be painted simultaneously, delivering a smooth, flawless, and durable finish without having to treat each surface type separately. When mixed directly into paint, it doubles as a flex agent, increasing the finished coating's flexibility on plastic panels and reducing the risk of cracking or delamination over time. The quick-dry, no-mix formula also fills 320-grit scratches, streamlining the prep process.

Bulldog® Adhesion Promoter Plus

For shops looking to cut steps without cutting corners, Klean-Strip also offers Bulldog® Adhesion Promoter Plus — an advanced single-component, ready-to-spray formula that eliminates the need for a separate primer or sealer altogether. It dries in as little as 5 minutes, is shade-adjustable, reduces basecoat usage, and works on pre-painted metal, plastic, and aluminum. The time and material savings make it especially popular in high-volume refinishing environments.

Backed by a Warranty

Perhaps the most telling sign of Klean-Strip's confidence in the Bulldog line is the Lifetime Warranty offered when using the complete Bulldog® System. That kind of backing is rare in the world of surface prep chemicals and speaks to the consistent, repeatable results these products deliver job after job.

Available in aerosol, quart, and gallon sizes, Klean-Strip adhesion promoters are designed to fit every scale of work — from a quick trim repair in a home garage to full production runs in a professional body shop.
