Boat Detailing Kit
Share
The white that comes off on your hand is oxidized gelcoat, and gelcoat is a different material from car paint in ways that change what you buy. It is a thick pigmented polyester resin, sprayed into the mold before the hull is laid up, with no clear layer over the top. So the color you are looking at is the surface itself, chalking as it weathers. Three containers here: a wash, an all in one for the chalky sections, and a gallon of wax because a hull is a great deal of surface area.
Gelcoat is not clear coat
A car has a few microns of clear over its color, which is why detailers talk about paint thickness gauges and only correcting a panel two or three times in its life. Gelcoat is measured in a different order of magnitude and it is pigmented all the way through. That is why a chalky hull can be cut back hard and come up glossy, where the same approach on a car would go through the clear in a heartbeat. It also weathers differently, since ultraviolet attacks the resin at the surface and leaves that powder behind rather than a fading film. The rest of what we stock is in the Wash Bay, and the other situational kits are on the bundle guides hub.
Wash, cut and wax on a hull
Wash N Wax starts it, and a boat gives it more to do than a car does. A hull sitting on a trailer or in a slip picks up a film of dust, exhaust soot and whatever the water leaves at the waterline, and none of that comes off with a hose alone. 3D lists it for cars, trucks, sport utility vehicles, boats, aircraft, motorhomes and motorcycles, by hand bucket or through a foam gun, so the same jug covers the tow vehicle on the way home. Wash the whole boat, including the transom and the underside of the rubrail, before you decide which sections actually need correcting.
The Marine and RV All-In-One is the correction step and the reason this is a separate kit rather than a car one. 3D built it with what the maker calls Adaptive Abrasive Technology, and states it maximizes cut rate up to 2000P sand marks while providing a deep shine on gel coat surfaces. That range means one liquid covers both the heavy chalk and the finish pass, and 3D notes the formula is filler free, so the gloss you get is real rather than an oil sitting in the porosity until the next rain. 3D says to cut with a wool pad and finish with a foam pad, changing only the pad between passes.
Xpress Wax is the protection layer and it comes as a gallon on purpose. P&S says it quickly brightens and protects, and describes it as combining the natural protection factor of carnauba wax with high tech polymer waxes to produce long lasting protection with high quality depth and shine. P&S also says it is designed for fast and easy application on a wide variety of vehicle finishes, which is the property that matters when the surface in front of you is twenty feet long rather than a hood. Fresh gelcoat straight after correction is open and hungry, so waxing the same day is not optional.
What you still have to supply
Pads and a machine. 3D's own method calls for wool to cut and foam to finish, and neither is included here, so check what you already own before this arrives. The heavier cutting compound in the add ons is for the sections the all in one will not clear on its own, usually the topsides that face the sun all season, and buying it up front is reasonable on a badly chalked boat. No hull cleaner for the waterline stain is included either, since that is an acid job with its own rules and it belongs in a different order.
Working a hull without losing a weekend
Break the boat into sections and finish each one completely before moving on. A hull is large enough that working by stage across the whole thing leaves you with half a job at sunset.
- Wash the whole boat and let it dry.
- Test a section about a yard square with the all in one on a wool pad, then finish it with foam and look at it in daylight.
- If that clears the chalk, carry on section by section along the topsides.
- For anything the all in one leaves behind, step up to the cutting compound and then refine with the all in one afterwards.
- Wipe each corrected section down before you wax it.
- Wax the whole boat last, working out of the sun, and do the transom first while you still have energy.
Do the vertical surfaces before the deck. Anything that runs down onto a corrected topside is easier to deal with than the other way around, and the deck takes non slip treatment rather than wax anyway.
What the gallon sizes replace
A pint of wax will not get you around a boat, and finding out halfway along the port side is the worst possible time to discover it. That is why the wax here is the gallon. The correction liquid is a quart, which is honest rather than generous, so on a badly chalked hull order a second one with the first rather than after.
The same three containers cover an RV, which is the other surface nobody has enough product for. Pal Automotive items are sold and shipped by Pal Automotive through Shopify Collective, not made or shipped by Sniff and Shift. Sizes and the heavier compounds can be compared on Explore.
Gelcoat questions we get
Can I use car polish on a boat?
You can, and on light oxidation it will work. It runs out of cut long before heavy chalk gives up, which is why the marine liquid exists and why a hull takes a different bottle from a hood.
How often does a hull need this?
The full correction, every few seasons depending on how much sun it sees and whether it is covered. The wax, at least once a year, and twice is better for a boat that lives outside uncovered.
What about the non slip deck?
Leave wax off it. Gloss on a walking surface is the last thing anybody wants on a wet deck, and textured non slip holds product in the pattern where it goes gray and sticky.
