It provides high levels of protection against abrasion, stone chip damage, and corrosion.

The non-stringing formulation holds brush marks well so that OEM finishes can be replicated.

With solids content in excess of 50%, this product will outperform competing materials.

• Single pack air curing seam sealer.


• Perfects and protects seams with OEM quality finish and appearance.


• Easy-to-use non stringing formulation.


• Grey finish to compliment all top coats.

How to use:

Ensure that surfaces are dry and free of any contamination, degrease thoroughly with panel-wipe or clean solvent such as Xylene.

Apply Dynax-Seam generously and evenly with a brush along the seam. Achieve a dry film thickness of 200 microns over thinnest point.

Drying time will vary with temperature, humidity and air movement, but typically 6-10 minutes to surface dry and 8-10 hours to fully cure.

Accepts a wide range of paint finishes once fully cured.

Always test at small scale your chosen paint system in full before use.
