Soft99 Hydro Flash Spray Coating

Add the recommended amount to your wash bucket or foam lance solution, wash the vehicle as normal, and rinse thoroughly. The coating deposits onto the paintwork during the wash process. Dry the car as you normally would and the hydrophobic layer is already in place - no separate spray or buff step required.

Yes. Smooth Egg Hydro Flash is compatible with existing ceramic coatings and paint sealants. It works well as a maintenance wash product that tops up the hydrophobic properties of an underlying coating, keeping the surface slick and the beading strong between full maintenance sessions.

Absolutely. There are no fillers or abrasives in this product, so it is safe on all paint colours including black, dark blue, dark grey, and metallic finishes. On dark paint the slickness and water-beading effect are especially visible after drying.

The product is designed primarily for painted body panels. On glass it will help water bead but dedicated glass coatings will outperform it there. Avoid contact with matte or satin finishes as the coating chemistry is optimised for gloss surfaces. Check that any wheel or trim surface can tolerate shampoo-based coatings before using.

The coating layer is intended as a wash-stage booster rather than a long-term standalone coating. Protection and hydrophobicity are refreshed with each use, so the more regularly you wash with Smooth Egg Hydro Flash, the more consistently slick and protected the surface stays. For long-term durability, a dedicated sealant or ceramic base coat underneath is recommended.

When rinsed and dried properly, it leaves no streaking or white residue. A thorough rinse after washing is important - any product pooling in panel gaps or on trim should be flushed out with a strong rinse. A clean microfibre drying towel finishes the job cleanly.

Yes, it can be added to a foam lance or foam cannon solution. Bear in mind that dilution ratios will vary depending on your lance setting and pressure washer output. Start conservative with the amount and adjust based on the slickness and beading you get after drying. A two-bucket method works just as well.

Smooth Egg Hydro Flash works well as part of a broader Soft99 care routine. It is compatible underneath or over other Soft99 waxes and coatings used as maintenance layers. For best results, ensure the base paint surface is decontaminated and any correction is done before relying on this product to maintain the finish.
