Half a puff of FSE and wipe where I see any marks. Wipes them out first time everytime!\nLeaves the car perfect! Works on glass and chrome also. As well as unpainted plastics plus excellent on gloss black wheels\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nView this post on Instagram\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nA post shared by Slim's Detailing (@slimsdetailing)\n\n\n ","images":["https://cdn.shopify.com/s/files/1/0427/6758/1340/files/fse-1l.png?v=1771587774","https://cdn.shopify.com/s/files/1/0427/6758/1340/files/fse-action.jpg?v=1771587895","https://cdn.shopify.com/s/files/1/0427/6758/1340/files/fse-action1.jpg?v=1771587894","https://cdn.shopify.com/s/files/1/0427/6758/1340/files/fse-action2.jpg?v=1771587894","https://cdn.shopify.com/s/files/1/0427/6758/1340/files/fse-action3.jpg?v=1771587895"],"price":12.05,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:27:00.519Z","product_rating":null,"product_rating_count":0,"seller_rating":null,"seller_rating_count":0,"units_sold":0,"reviews":{"count":0,"top":[]},"videos":[]},"share_url":"https://firestarter.network/l/lst_aijK-sq_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
