Step-by-step instructions

⚠️ IMPORTANT NOTES

Surface Prep:
Before using SKWOL™ Formula 4, it's important to make sure surface is clean, dry, and cool to the touch. Do not apply in extreme temperatures or in direct sunlight.

Maintenance:
This product was specifically formulated to help you clean your boat while maintaining your protective coatings. Avoid the use of cleaning products that contain the following ingredients as they are proven to strip wax, polish and ceramic:

• Degreasers (Simple Green, Most Boat Soaps and Dish Soaps etc.)

• Bleach (Bathroom Cleaners, Household disinfectants etc.)

• Harsh Acids (Spray Nine, Vinegar, Barkeeper Friend, and many Hull Cleaners)

NOTE: If you do use products that contain ingredients like the above, it is recommended that you neutralize the surface and re-apply protection. We develop all of our formulas to work together and therefore recommend cleaning with SKWOL™ Wash & Prep and Formula 4, which are both pH neutral solutions that are free from degreasers, harsh acids and bleach, and protecting your boat with our longest-lasting ceramic spray in its class: SKWOL™ Deck & Hull Ceramic Top Coat

Step 2: Spray & Wipe

Spray product on the surface and allow it to sit for up to 30 seconds without drying. Wipe clan with a microfiber cloth.

For black streaks or heavier soiling, after spraying product onto surface, agitate with a soft-bristle detailing brush, allow to sit for up to 30 seconds without drying, and wipe clan with a microfiber cloth.

NOTE: Waiting too long between spraying and buffing can make product challenging to apply as Deck & Hull is designed to set quickly.
