The guys at Zippy Klean did a great job buffing the scratched up dull paint job on my old Prius and making it shine like new. Appreciate, the really professional, friendly and speedy service, which included dropping me by a coffee shop while I waited. Couldn't be happier with Steven's team. Thanks!

One pass. Less than half the price.
Plenty of hulls that look tired only need a single cut-and-polish pass, not full multi-stage compounding. We do a free test section before quoting, because quoting the expensive job on a hull that needed the cheap one is how people get overcharged.

Visual proof
One step, where one step is enough
Light fading, water spotting and a loss of depth are a single-stage job — one pass, polish and seal, done in a fraction of the time heavy correction takes. The honest part is telling you when it is not enough, because a one-step on a chalked hull just hides the problem for a month.
Before — flat and spotted, but the gelcoat is still alive
After — one pass, polished and sealed
Half polished, half untouched — on the same panel
This one needs cutting, not polishing — we will say so
One pass, done properly
What single-stage does
A combined cut-and-polish pass over every square foot: enough abrasive to remove a light oxidised layer, finished fine enough to leave gloss rather than haze.
- Removes light oxidation — the flat, dull layer that makes gelcoat look tired without being chalky
- Restores reflection — the difference between clean and glossy
- Takes off light staining — waterline scum, exhaust marks, rust bloom
- One pass, not three — which is where the price difference comes from
- Leaves a surface ready to protect — freshly polished gelcoat is the most receptive it will ever be
What it does not do: reach sound gelcoat under heavy chalking. That needs multi-stage compounding, and if the test section shows you need it we will tell you.
Settle it before you book
Is single-stage enough for your hull?
The hand test
- Wipe a dry palm across the gelcoat
- Comes away clean, finish looks flat and lacks reflection — single-stage will usually bring it back
- Comes away visibly chalky — that is dead resin, and it needs heavy compounding
We do a free test section before quoting. Twenty minutes, a small area polished, and you can see the result instead of taking our word for it. If single-stage is not getting there, we say so and you decide. No pressure either way.
And then protect it. Polishing exposes fresh resin, and fresh resin under a UV index of 11+ starts degrading immediately. Bare, you will be back here in a couple of years. Protected, it holds.

What it costs
Prices shown are cash prices. Pay by cash or check and that is what you pay. The card price is shown in grey beside every figure — slightly higher, because card processing costs us that. Nothing is added at checkout either way: both prices are on the page before you book.
Hawaii GET is added at invoice and shown as its own line, at the state maximum visible pass-on of 4.712% (4% state + 0.5% Hawaiʻi County surcharge). Prices on this page do not include it.

Non-skid is quoted separately and is never polished smooth — that would make your deck dangerous. The per-foot price covers the whole hull up to the rub rail; the deck and everything above it is quoted on inspection.
Travel fee $50$52 card past 20 miles outside the Kona district. Gas on this island runs well above the mainland and the run to Waimea, Hawi or Hilo is real time in the truck — that fee goes straight to the technician working your job, not onto the service price. No fee if you drop off at our Kona shop near Magic Sands Beach Park — we give you the exact address when you book. We tell you the travel fee when you book, never when we arrive.

Straight answers
Single-stage polishing questions
How much does single-stage gelcoat polishing cost?
Single-stage oxidation removal is $25.00 per foot of overall length. A 24-foot hull is $600; a 32-footer is $800.
That is well under half what heavy multi-stage compounding costs, which is why it is worth finding out which one you actually need before booking.
Horse trailers and other gelcoat surfaces are $15.00 per foot of length for a light buff.
How do I know single-stage is enough?
The hand test: wipe a dry palm across the hull. If it comes away clean but the finish lacks reflection and looks flat, single-stage will usually bring it back. If it comes away visibly chalky, you need the heavy job.
We do a free test section before quoting — a small area polished so you can see the result rather than take our word for it. It takes twenty minutes and it settles the question.
If the test shows single-stage is not getting there, we tell you, and you can decide whether to go heavy. No pressure either way.
What is the difference between single-stage and multi-stage?
Passes. Single-stage is one combined cut-and-polish pass over every square foot. Multi-stage is compound, then refine, then polish — three full passes.
The cost difference is almost entirely labour. Three passes over a 32-foot hull is a very different day from one.
The result difference is how much dead gelcoat comes off. Single-stage removes a light oxidised layer and restores gloss. Multi-stage cuts deeper to reach sound gelcoat under heavy chalking.
How long will the result last?
On bare gelcoat, not long — it starts oxidising again from the moment it is exposed, and Hawaiʻi has the highest sustained UV load of any U.S. state.
This is the part worth understanding before you spend the money. Polishing removes a layer of dead gelcoat and exposes fresh resin. Fresh resin under an 11+ UV index begins degrading immediately.
Protected, it holds for years. Ceramic Infused Super Protection at $12.00 per foot gives you six to twelve months here; Stealth Diamond Borograph at $65.00 per foot is permanent and takes the UV instead of the gelcoat.
Can I just wax it instead?
Wax will make lightly oxidised gelcoat look better for a few weeks, but it is sitting on top of the oxidised layer rather than removing it.
That is a legitimate thing to buy if you want the boat to look good for a weekend. It is not the same as polishing, and anyone selling it as a fix for oxidation is being loose with the word.
The difference shows up in a few weeks when the wax goes and the dullness is still there, because it was never removed.
Do you polish the whole boat or just the hull?
The per-foot price is the whole hull, up to the rub rail. The deck, console, cabin sides and anything above the rub rail are quoted on inspection.
The hull is one large continuous surface, so a per-foot price is honest there. Above the rub rail is hardware, windows, rails and non-skid, and no two boats are alike — pricing that by the foot would mean overcharging simple boats to cover complicated ones.
Non-skid is handled differently from smooth gelcoat and is quoted separately — polishing non-skid smooth would make your deck dangerous.
