From light swirls to heavy oxidation, Aquatech's marine polish system restores gelcoat, paint, and fiberglass to a mirror finish — and protects it from the sun, salt, and water that wear it back down. Professional-grade, USA-made, and built to work together as a complete three-step compound-polish-finish system.
Compounds for heavy oxidation and deep scratch removal
Polishes for daily shine, swirl correction, and protective gloss
Pads and applicators sized for hand or machine buffing
Works on gelcoat, fiberglass, marine paint, and metal
Professional detailers don't pick one polish and call it done. Gelcoat and marine paint respond best to a graduated cut-polish-finish sequence — with each step designed to undo the work of the previous one just enough to prep the surface for the next. Aquatech's polish line is built to follow that system without the guesswork.
If your gelcoat still beads water and looks glossy, you're at Premier Polish or Ultra High Gloss Polish territory. If surfaces look dull but feel smooth, start with Marine Polishing Compound. If gelcoat feels chalky, looks faded, or has deep scratches, you need Buff & Cut Compound as your first step. Most serious restoration jobs use all three in sequence.
Everything you need to know about choosing, using, and caring for your boat with Aquatech polishes and buffing compounds — answered by the people who make them.
Whether you're restoring a neglected hull or maintaining a show-quality finish, the right polish system makes all the difference. Below are the questions we hear most often from boat owners and marine detailers — covering everything from how to choose between a compound and a polish to how often you should buff your gelcoat. If you don't see your question here, reach out directly and we'll answer it.
What's the difference between a marine polishing compound and a polish?
A compound is coarser — it physically cuts the top layer of oxidation and scratches off the surface. A polish is finer — it removes the haze left by the compound and adds a protective gloss. Most restoration jobs use both: compound first to correct, polish second to finish. For lightly-worn surfaces, you can skip straight to polish. For heavily oxidized gelcoat, you may need Buff & Cut Compound before the polishing compound.
Can I use Aquatech polishes by hand, or do I need a buffer?
Both work. Premier Polish and Ultra High Gloss Polish are designed to be hand-applied with a wax applicator pad. Marine Polishing Compound works by hand on small areas but goes faster on a machine buffer at 1,500–2,000 RPM. Buff & Cut Compound is designed for machine use — hand application is possible on spot corrections but won't remove heavy oxidation efficiently.
How do I know which polish or compound my boat needs?
Run your hand across the gelcoat. If it feels smooth and still beads water after a wash, use Premier Polish or Ultra High Gloss Polish. If it looks dull but feels smooth, start with Marine Polishing Compound. If it feels chalky or rough and looks faded, you need Buff & Cut Compound first, then move to Polishing Compound and finish with Ultra High Gloss.
Are Aquatech polishes safe on colored gelcoat and painted surfaces?
Yes. Every Aquatech polish and compound is tested safe on gelcoat (all colors), marine paint, fiberglass, metal, and polyurethane yacht finishes. For dark-colored gelcoat, use the Polishing Pad (foam) rather than a wool buffing pad to avoid swirl marks.
How often should I polish my boat?
A standalone polish with Premier Polish or Ultra High Gloss Polish twice per season is enough for most boats — usually once at spring commissioning and once mid-summer. Boats with heavy sun exposure or saltwater use benefit from a full compound-polish-finish restoration every 2–3 years to reset the gelcoat.
Do Aquatech polishes contain abrasives?
Compounds (Buff & Cut, Polishing Compound) contain micro-abrasives sized to cut oxidation without scratching. Finish polishes (Premier Polish, Ultra High Gloss Polish) contain polymer chemistry rather than abrasives — they clean, fill, and protect without removing surface material.
