Its primary benefit is the high-build filling capacity that smooths imperfections quickly, though users should be aware that as a 1K product, it requires proper ventilation and careful sanding to achieve a glass-like finish compared to 2K alternatives.

Clear the nozzle by inverting the can and spraying until clear, or soak the nozzle in thinners if blockage persists.
Apply thinner, more frequent coats rather than one heavy pass, and increase the distance between the can and the surface.
Ensure the surface was adequately sanded and fully degreased with a solvent cleaner before priming.
Before application, ensure the substrate is clean, dry, and free from wax, grease, and silicone by using a degreaser. Sand the surrounding area with P320-P400 grit to ensure proper mechanical adhesion. For best results, use the product in a well-ventilated area with appropriate respiratory protection. After use, invert the canister and spray for two seconds to clear the nozzle, preventing clogs for future use. Store the canister in a cool, dry place away from direct sunlight to maintain the integrity of the propellant and formula.
