10 "Marine Grade" Scams You Can Buy For $5 At The Hardware Store

Описание: Walk into any marine supply store, and you are walking into a trap. They take a standard $2 industrial part, wrap it in blue plastic, stamp "Marine" on it, and charge you a 400% markup. They call it "Quality Assurance." I call it the "Marine Tax."

In this video, we expose 10 "Marine Grade" Scams You Can Buy For $5 At The Hardware Store. We walk you through the industrial supply chain—from Grainger to McMaster-Carr—to reveal the exact part numbers, chemical formulas, and engineering standards you need to bypass the chandlery and get the same engineering for a fraction of the cost.

In this video:
🧪 The "Hull Stain" Secret: Why that $30 bottle of "Marine Gelcoat Restorer" is actually just $2 worth of Oxalic Acid (CAS 144-62-7) you can buy at the paint store.
⚡ The Welding Cable Hack: Why professional welders use "Royal Excelene" cable that is superior to "Marine Battery Cable" for half the price (and yes, it's tinned).
🔧 The SAE Hose Code: How to read the SAE J20R3 code on a heater hose to prove that the $2/ft auto parts hose is identical to the $10/ft marine hose.
🔩 The Blister Pack Tax: Why you should never buy stainless steel bolts from a marine store, and the specific McMaster-Carr part numbers to order instead.

👇 The Verdict:
The fish don't know how much you paid. Are you paying for the engineering, or are you paying for the blue box? Watch this before your next haul-out.
