Marine Detail Supply Charleston is a walk-in store at 7644 Southrail Rd in North Charleston. From here the Ashley River and Cooper River landings are a short drive, downtown Charleston and Daniel Island are about twenty minutes away, and the barrier islands from Folly Beach to Isle of Palms are within about forty-five minutes. Kiawah is the longest run on our list, a little over an hour without traffic.
Boating here is a big deal. SCDNR counted 30,337 boats registered in Charleston County in 2025, 17,079 in Berkeley and 8,522 in Dorchester: more than 55,000 across the three counties. Charleston County Parks alone maintains 19 public boat landings. Much of the water they run in is salt or brackish, under strong sun and heavy humidity, and with a tide that swings around five and a half feet at the downtown marina. That mix is what we stock for: salt washes and rinse-safe sealants for weekly care, compounds and polish for chalky gelcoat, coatings that make the next season easier, and mildew control for everything with a cushion or a canvas top.
You can get what you need two ways. Stop in during store hours to see the products, ask questions and leave with what you need. Or shop online: free shipping on orders over $200 (UPS Ground) and a $7 flat rate on orders under $200. We don’t offer delivery, so it’s the store or UPS Ground.

Six products that cover most of a Charleston boat’s year: rinse the salt, fix the oxidation, protect the gelcoat and keep mildew out.
A Lowcountry boating year
There’s no real off-season here, just busier and quieter months. Here’s what to plan for.
Spring and summer
- Start the season with a proper wash and an honest look at the gelcoat. If it’s chalky, plan a compound and polish before you add protection. Coatings and sealants go on best over a corrected surface.
- Rinse salt off after every trip, before it dries into a film. A pH-neutral salt wash won’t strip the sealant or coating underneath.
- Summer sun works on everything, including vinyl, canvas and the gelcoat on the bow. Top up protection through the season instead of waiting for it to fail.
Fall and winter
- Humid weeks and closed-up cabins are when mildew starts. Clean soft surfaces, let them dry fully, and treat them before the boat sits.
- Fall and winter are good months for correction work. It’s cooler under the T-top, and the boat is used less, so you can take the time to do it right.
