If you’ve spent any time in the modern car restoration rabbit hole on YouTube, you’ve probably come across the running joke: “Mansory glue.” Fans of Mat Armstrong often jokingly call it “Mattsory glue,” a tongue-in-cheek nod to the extreme builds of Mansory. But behind the meme is a very real and very effective tool of the trade.
The Reality Behind the Meme
In practice, what Mat is using isn’t some mysterious, exotic bonding agent. It’s a tried-and-tested polyurethane adhesive called Tiger Seal.
This one-component, ready-to-use sealant is a staple in body shops for a reason. It bonds aggressively to a wide range of materials—steel, aluminium, and most plastics—making it ideal for securing body kits, carbon fibre components, splitters, and trim pieces. Whether you’re rebuilding a crashed supercar or fitting aftermarket aero, it delivers a strong, flexible hold that can withstand vibration and environmental stress.
Unlike rigid adhesives, Tiger Seal remains slightly elastic once cured. That flexibility is key in automotive applications, where panels expand, contract, and flex under load. It also doubles as a sealant, helping prevent water ingress around joins and seams. Tiger Seal is available for purchase online here.
A Worthy Alternative
Of course, Tiger Seal isn’t the only option on the market. Another widely respected product is Sikaflex-227.
Like Tiger Seal, Sikaflex-227 is a one-component polyurethane sealant designed specifically for automotive bodywork. It cures when exposed to atmospheric moisture, forming a durable elastomer that adheres well to a broad range of substrates.
Where it stands out:
- Fast skinning time, which speeds up installation
- Low odour, making it more workshop-friendly
- Non-shrinking formula for consistent results
- Permanent flexibility, crucial for long-term durability
- Paintable finish, allowing seamless integration into bodywork

Why Car Builders Swear By It
The popularity of these adhesives—both in professional workshops and among DIY builders—comes down to versatility. Mechanical fasteners still have their place, but polyurethane adhesives offer a cleaner finish, distribute stress more evenly, and reduce the need for drilling into expensive panels.
That’s exactly why creators like Mat Armstrong rely on them in high-stakes rebuilds. When you’re piecing together damaged supercars or fitting bespoke body kits, you need something that’s quick, strong, and forgiving.
The Bottom Line
“Mansory glue” might be a meme, but the products behind it are no joke. Whether you choose Tiger Seal or Sikaflex-227, you’re getting professional-grade bonding solutions that have earned their place in the modern restoration toolkit.
For anyone stepping into the world of body kits and custom builds, these adhesives aren’t just convenient—they’re essential.
