Hi There! ProtectaClear is perfectly suited to your situation, but we would recommend PC279 instead. This product is designed to withstand environmental and chemical corrosion in coastal areas. We recommend neutralising and preparing the stainless steel surface with Cr24 Stainless Steel Deep Cleaner before applying ProtectaClear or PC279. If your stainless steel surface has developed rust, you can use ERW-XL rust remover to remove it. For routine maintenance, please avoid abrasive pads or harsh chemicals to maintain the finish and coating integrity. Hope this helps :)
