Dominion Sure Seal Epoxy Repair Kit

Dominion Sure Seal Epoxy Repair Kits

Cracked bumper covers, torn plastic trim, and gouged body panels are among the most common repairs in a collision shop. Dominion Sure Seal approaches them with its Sure Seal Plastic Surgery line, a family of two-component modified epoxies engineered to repair gouges, tears, holes and scratches on plastic. Rather than a generic all-in-one glue, these kits are built around the way plastic parts are actually repaired: bond the crack, fill the damage, then sand and feather the repair for paint.

What Sets Plastic Surgery Epoxies Apart

Dominion Sure Seal has been manufacturing sealants, protective coatings and adhesives for the automotive paint and body industry since 1972, and the company credits itself with creating the first OEM-approved plastic repair line. That background shows in the way the Plastic Surgery epoxies are formulated. They work much like a traditional polyester filler, but are designed specifically for plastics, and they can be used as both an adhesive and a filler on the front and back sides of a repair.

The line is organized by the type of plastic you are working with:

• All Purpose (semi-rigid): Formulated to work on common plastics as well as the traditional "tough to bond" types such as TPUR, PUR, RIM, PP, TPO and TPE. It is known for easy sanding and feather-edging, and is often used as a glaze coat over plastic surfaces.
• Flexible: Intended for flexible plastics such as TPUR, PUR, RIM, PP, TPO and TPE, where a repair needs to move with the part rather than crack along its edge.
• Rigid: Designed for rigid substrates such as SMC, BC and RTM.

Choosing the Right Formula

Matching the epoxy to the substrate is the most important decision in any plastic repair. A semi-rigid all-purpose filler suits many bumper covers and general plastic parts, while a flexible formula is the better choice for pliable fascias and trim that flex in service. The two-part format, with separate Part A and Part B tubes mixed on the bench, gives you working control and a cure that develops uniformly through the repair. For tears and holes, Dominion Sure Seal recommends pairing the epoxy with a plastic welder or its own welding tape for the strongest result.

Some kits go beyond the epoxy itself. The Plastic Repair Kit configuration pairs two-part semi-flexible epoxy with fast-cure CA adhesive, mesh fiber tape and mixing sticks, so you can tack a break in place, reinforce the back side and then build up the repair. It is designed for bumpers and general plastic parts on cars and boats, and it bonds to most plastics, glass, wood and metal.

Who These Kits Suit

Body shops use this type of repair to keep salvageable bumpers and plastic components out of the scrap bin, while restorers and DIYers can use it for fender liners, trim tabs, mounting ears and similar damage. Whatever the application, good results depend on clean, properly prepared surfaces and accurate mixing of both components.
