Can I Sand and Recoat My Resin Roll Bar?

If you’re aiming to restore the finish or enhance the strength of your resin roll bar, sanding and recoating is a practical solution. This process can refresh the appearance and prepare the surface for an additional protective layer.

How to Sand and Prepare Your Resin Roll Bar

Before recoating, it’s crucial to ensure your roll bar resin is fully cured. Once cured, carefully sand the surface with fine to medium grit sandpaper—typically starting around 200 and working up to 400 grit for a smooth result. Sanding helps the new coat adhere properly by dulling any gloss and removing imperfections.

After sanding, thoroughly clean away all dust and debris. A lint-free cloth and a suitable cleaning solution, such as isopropyl alcohol, can help create a spotless, residue-free surface ready for recoating.

Tips for Applying an Additional Resin Coat

Select a compatible resin for your project; for carbon fibre or fibreglass roll bars, an epoxy resin designed for fabric impregnation—like the “Carbon Resin” Epoxy—ensures strong bonds and a flawless finish. Work in a dust-free area and apply the new layer evenly using a brush or roller. Allow the coat to self-level and cure as directed by the resin manufacturer. Avoid overworking the resin to reduce bubbling and surface marks.

When Recoating Matters Most

If your roll bar surface has become scratched, cloudy, or worn, recoating restores clarity and gloss.
If you need to increase the thickness for structural improvements, adding a layer following proper sanding helps achieve this safely and reliably.
