FAQs
Can I use this on non-automotive projects?
While designed for automotive seams, its synthetic rubber properties make it suitable for sealing any overlapping metal joints requiring a flexible, weather-resistant seal.
Does it need to be painted over?
While it can be left exposed, painting it protects the sealant from UV degradation and ensures a uniform color match to the vehicle body.
What tools do I need for application?
A standard nylon bristle brush is sufficient to apply and texture the seam sealer effectively.
Can I use this in cold weather?
The 2-hour cure time assumes 20 degrees Celsius. In colder temperatures, the curing process will be significantly delayed.
Is this product water-based?
No, it is a synthetic rubber-based sealant, which is why proper surface degreasing is required for a permanent bond.
Troubleshooting
The sealant is running or slumping during application
Ensure the surface is not too smooth and check the temperature. If it is too warm, the material may thin; move to a cooler environment.
Sealant is not adhering to the metal
The surface was likely not cleaned properly. Strip the area, degrease thoroughly with panel wipe, and reapply.
Paint is cracking over the sealer
You likely applied the paint before the 2-hour cure time or applied more than two coats of sealer. Ensure full cure and follow coat limits.

Setup, Compatibility & Care
To ensure optimal adhesion, the metal surface must be completely free of oil, wax, and dust. Using a professional-grade product like Tetrosyl Compliant Panel Wipe is highly recommended for the initial cleaning phase. Apply the sealer using a high-quality nylon brush, ensuring even distribution across the seam. Do not apply more than two coats, as excessive thickness can impede the curing process or cause cracking. Allow the product to dry for a minimum of 2 hours at a constant temperature of 20 degrees Celsius before applying any topcoat. Always store the containers tightly sealed in a cool, dry place when not in use to prevent the rubber base from thickening.
