［Q］		Is it got the effect even if I mix BARNACLE GUARD with any ship bottom paint?
［A］		BARNACLE GUARD is suitable for hydration-degradation (self-consumable ) type (self-abrasive,  self-polish) ship's bottom paints. It is not suitable for hydrolytic and silicone bottom paints.

［Q］		Barnacle adhesion prevention effect do you persist BARNACLE GUARD really?
［A］		The durability of the effect is proportional to the thickness of the coating film applied with Barnacle Guard mixed in. By mixing BARNACLE GUARD with a hydration-degradation type (self-consumable type) ship bottom paint, BARNACLE GUARD, which is time encapsulated by a special surface treatment, continues to appear on the painted surface as the paint decomposes in the sea, preventing barnacles and mussels from attaching to the surface. The BARNACLE GUARD is effective as long as the paint film remains on the surface. Therefore, two or more coats are recommended for long-lasting effectiveness. （Even with two or more coats, the paint degradation period may be short or long depending on the ship's operating rate and the nature of the bottom paint.) Some hydrolysis type ship's bottom paints may degrade faster than usual depending on the environment when BARNACLE GUARD is added, so please use self-polish ship's bottom paints that have stable effects.

［Q］		Does the effectiveness of BARNACLE GUARD vary depending on the sea area where it is used?
［A］		Barnacles and mussels attach to ship bottoms as larvae, but the activity of the larvae varies depending on the sea area, and the antifouling function of ship bottom paints based on "poisons" such as copper oxide varies depending on the activity of the larvae. In saltwater areas facing the open sea, where there is no river confluence, the salinity is high and this suppresses the activity of the larvae, making it easier for the "poison" to be effective. Therefore, since the effectiveness of the poison depends on the activity of the larvae, the effectiveness of ship-bottom paint alone varies depending on the sea area. BARNACLE GUARD does not deprive (weaken) the larvae of their vitality, but rather disables the larvae's attachment function itself. Therefore, when BARNACLE GUARD is added to ship-bottom paints, its effect is demonstrated regardless of the activity of the larvae, so there is no difference in the anti-adhesion effect depending on the sea area.

［Q］		Does BARNACLE GUARD have a use-by date? Also, can I use the leftover barnacle guard the following year?
［A］		There is no expiration date, if the state of being sealed unopened. Unplug the air in the package, close the chuck firmly at the top, please store it in a place where no direct sunlight in a state of being closed the rest of after use. It can be used without compromising the effect for about two years after opening if so.

［Q］		I have leftover ship's bottom paint mixed with BARNACLE GUARD, can I use that paint again the following year?
［A］		Keep the lid of the paint can tightly closed and sealed. If the paint has not cured, it can be reused the following year without loss of effectiveness. When reusing, be sure to stir the paint well before use.

［Q］		Can I use on all ships BARNACLE GUARD?
［A］		It is not suitable for aluminum and light alloy vessels, but can be used with a primer specially designed for aluminum and light alloy ships. It can also be used on vessels with hull materials other than aluminum and light alloys, such as FRP, iron (steel), and wood, without any problem, making it ideal for barnacle prevention.

［Q］		Can BARNACLE GUARD be mixed with antifouling paint exclusively for propellers and shafts?
［A］		BARNACLE GUARD is dedicated ship bottom paint additive. Therefore can not be used in the propeller shaft for anti-fouling paints.

［Q］		Is there any problem if I apply the ship's bottom paint mixed with BARNACLE GUARD to metal parts such as drives and shafts?
［A］		Due to the nature of the product, BARNACLE GUARD may cause corrosion on aluminum, zinc, brass, brass and stainless steel if a ship's bottom paint mixed with BARNACLE GUARD is applied directly to these metals. If the drive unit, etc. is made of these metals, it is possible to apply BARNACLE GUARD-mixed ship's bottom paint over the primer or zinc-acrylic type ship's bottom paint corresponding to these metals before adding BARNACLE GUARD to the base coat. (As long as the metal is not in direct contact with the BARNACLE GUARD mixed bottom paint, there is no problem.)   Direct application of zinc-acrylic type ship's bottom paint mixed with BARNACLE GUARD to iron (steel) parts is not a problem at all. However, since BARNACLE GUARD is an additive for ship's bottom paint, please use it at your own risk when applying it to other than ship's bottom. *Copper acrylic type (copper oxide type) ship's bottom paint will cause electric corrosion on metals even without the addition of FUJITSUBO GUARD, so please avoid direct application on metal parts.
