Etalon 5300FP Universal Finishing Body Filler with White Hardener, 1kg

Fine Finishing Filler for Professional Surface Repairs

The Etalon 5300FP Fine Body Filler is designed specifically for finishing work where surface quality is critical.

Unlike heavier body fillers intended to rebuild large damaged areas, the 5300FP has a fine structure that makes it ideal for correcting small imperfections and preparing a smooth surface before the next stage of the refinishing process.

It is particularly useful for:

• Small pinholes
• Fine scratches
• Minor dents
• Small surface imperfections
• Irregularities left after previous filling work
• Final preparation before primer and paint

The result is a smoother, more uniform surface that requires less effort during final preparation.

White Hardener – Ideal for Yacht Refinishing

This specific version, ET5300FP-100/W, is supplied with white hardener.

Etalon specifically recommends the white-hardener version for yacht refinishing applications.

The advantage of the white system is particularly clear when repairing light-coloured or white yacht surfaces, as the repaired area remains visually neutral and does not introduce a strongly coloured hardener into the finishing layer.

This makes it an excellent option for professional:

• Yacht refinishing
• Boat repair
• GRP repair preparation
• Hull and superstructure refinishing
• Marine paint preparation
• Cosmetic surface restoration

Suitable for Multiple Surfaces

Etalon 5300FP can be used for finishing work on a variety of properly prepared substrates, including compatible:

• Metal surfaces
• Steel
• Galvanized steel
• Aluminium
• Fiberglass / GRP
• Previously repaired surfaces

This versatility makes it especially useful in yacht maintenance and refit environments, where different materials may be present across the same project.

Always confirm substrate preparation and compatibility with the complete refinishing system being used.

Ideal for Fiberglass & GRP Yacht Repairs

Fiberglass and GRP surfaces often develop small pinholes, sanding marks and minor surface imperfections during repair work.

The fine consistency of Etalon 5300FP allows these defects to be filled before applying primer or subsequent coatings.

It is especially useful during:

• GRP fairing repairs
• Gelcoat preparation
• Local surface repairs
• Refinishing work
• Primer preparation
• Cosmetic yacht repairs

For deeper structural repairs or large cavities, a heavier filling product may be required first. The 5300FP is best used as the final fine finishing layer.

Excellent for Closing Pinholes

Pinholes can remain visible after sanding heavier fillers or repairing fiberglass surfaces.

If they are not properly filled before priming and painting, they can become visible in the final coating.

The fine structure of Etalon 5300FP is designed to help close these small defects and create a smoother base for subsequent refinishing stages.

This makes it particularly valuable when the goal is a high-quality yacht finish.

Easy Sanding by Hand or Machine

One of the key advantages of Etalon 5300FP is its easy sanding characteristics.

Once correctly cured, it can be sanded:

• By hand
• With an orbital sander
• With professional body-shop sanding equipment

Easy sanding reduces preparation time and makes it easier to achieve a smooth transition between the repaired area and the surrounding surface.

This is particularly important in yacht refinishing, where large smooth surfaces make even small imperfections highly visible after painting.

2K Polyester Technology

Etalon 5300FP is a two-component polyester-based finishing filler.

The filler is mixed with the supplied hardener before application, initiating the curing process.

This provides:

• Fast professional curing
• Strong repair performance
• Fine finishing characteristics
• Easy sanding
• A stable base for subsequent refinishing work

Always use the hardener quantity and application conditions specified in the current Etalon Technical Data Sheet.

Why Choose Etalon 5300FP for Yacht Repairs?

High-quality yacht refinishing depends heavily on preparation.

Even the best primer and topcoat cannot completely hide poorly prepared pinholes, scratches or uneven repairs.

Etalon 5300FP allows the technician to carry out the final correction stage before priming, creating a smoother and more uniform substrate.

The white-hardener version is especially useful for yacht applications because it combines professional filling performance with a colour system suited to marine refinishing.

Professional Application Tips

For a better final finish:

• Correct major damage first with the appropriate heavier filler.
• Apply several controlled finishing passes rather than one unnecessarily thick layer.
• Keep the mixing surface and tools clean.

• Do not return mixed material to the original container.
• Remove sanding dust thoroughly before applying primer.
• Check the surface under good lighting before moving to the next refinishing stage.
