The 862 ml size is well-suited for moderate blister fields or a single large repair area — enough product to complete a typical job without waste. Customers should plan their repair sequence: open and dry blisters fully before applying, then sand fair before applying a barrier primer. If a customer is asking about the full blister repair system, confirm they also have a compatible marine primer and antifouling paint on hand to complete the job properly.\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564084756516,"sku":"3MR-46013","price":173.51,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/43c6d82d-f2a7-43e5-85c7-a0a5a85fb812.png?v=1785976989","url":"https:\/\/marisolmarine.com\/products\/3m-blister-repair-filler-862ml-3mr-46013","provider":"Marisol Marine Company","version":"1.0","type":"link"}
