Carlo Luongo's remarks
- The product is not harsh on the skin. You can safely use it even without gloves, just taking care to wash your hands well after use.
- The product does not run and there is no need to rinse, so it can be used even with the boat in the water.
- If you let the product dry on the surface, simply rinse with plenty of water and wipe it off. Always do a preventive test in a hidden spot if there are materials other than stainless steel.
- Flash Bright allows fast and targeted action, but does not remove rust For this it uses Squidy: Carlo Luongo shows you how best to use it.
- To avoid removing the protective coating, when you wash the boat , use neutral and not too harsh detergents, such as Caravel Shampoo and Wax. Watch the tutorial by Carlo Luongo.
