Distinguishing Between Body Kit Materials (IMPORTANT)

FRP (Fiberglass Reinforced Plastic) Body Kits: Unraveling the Mystery

FRP or Fiberglass Reinforced Plastic is predominantly used in the production of body kits. A common misconception is that it’s entirely made of “plastic.” However, FRP is largely composed of fibreglass, which solidifies upon the addition of a polyester-based resin. Many FRP kits have a gel coat finish, while others might just have a primer coating. The primary reasons for its extensive use include its affordable manufacturing cost and the ease with which the parts can be modified.

Clarification on FRP Characteristics: It’s pivotal to recognize that characteristics like scratches, sand weaves, and join lines in FRP parts are standard outcomes of their production. It’s not a sign of inferior quality. Such features are intrinsic to all FRP parts, regardless of who makes them. Properly prepping these components is vital before painting or vinyl wrapping. This ensures a smooth, impeccable finish, thus amplifying the part’s visual allure and safeguarding it. Therefore, when you spot such traits, comprehend that they aren’t defects – they’re typical of FRP parts.

Special Note: White FRP, particularly from Robot, is smoother than its black counterpart. This means it often requires less prep work before painting. However, producing the white FRP is a more challenging process, making it slightly rare.

All FRP body kits need some level of cleaning and detailed attention before painting. The primary drawback is their susceptibility to damage if there’s an impact. However, they have the advantage of being budget-friendly and repairable.

Polyurethane (PP) Body Kits: Flexibility at Its Best

Polyurethane takes the second spot in terms of popularity for body kit materials. Known for its rubber-like texture, polyurethane stands out for its immense flexibility and durability. Unlike a fragile fibreglass bumper, a polyurethane bumper can endure impacts without significant damage. On the downside, polyurethane kits are pricier to manufacture. The production method and mould designs add to the expense, making these kits less widespread than fibreglass ones. Additionally, polyurethane parts weigh more, often necessitating support brackets to avoid sagging.

The Elegance of Carbon Fiber Body Kits

Carbon Fibre is the premium choice for body kits. The kits exude luxury with their glossy protective finish over the carbon fibre weave. They don’t require painting but could benefit from a UV-protective clear coat. Carbon fibre is mostly chosen for components like bonnets, bumper lips, side skirts, and spoilers.


The Installation Process for Body Kits

“How do I install my body kit?” is a frequent query. Generally, full bumper replacement kits utilize the original equipment manufacturer (OEM) hardware from stock bumpers. The first step involves a dry fit to check alignment. Post this, you’d mark and drill mounting holes.

Tip: When drilling fibreglass, apply masking tape over the intended area and drill in reverse to prevent splintering.

Ensure the component is aligned right and all flaws are marked for rectification. For heavier polyurethane kits, custom brackets might be essential for proper support.


Choosing the Right Body Shop

Opt for customisation-centric shops over collision repair ones. Custom shops, familiar with body kits and unique paint jobs, are better equipped for such tasks.


Prepping Your Body Kit for Paint

Body kits aren’t always paint-ready. FRP kits need extensive prep – sanding, spotting defects, and using body filler for a smooth surface. Polyurethane parts require less work but need an adhesion promoter for paint bonding and a flex agent for paint flexibility. Carbon fibre kits, though not requiring paint, benefit from an automotive clear coat for a deeper finish and UV protection.
