3M Marine Finishing System Context

3M Finesse-It II sits in the intermediate-to-finishing range of the 3M polishing system — heavier than a pure ultrafine finishing polish, lighter than a cutting compound. Its specific strength is post-sanding use: after fine-grade wet sanding of gel coat or paint to remove deep scratches, orange peel, or runs, Finesse-It II removes the sand scratch haze and refines the surface to a high-gloss, wet-look finish before any final polish or protective coating is applied. It also excels at removing compound swirl marks left behind after machine compounding steps, making it a versatile intermediate finishing tool in both new-paint and repair workflows. 3M has been a leading supplier of marine surface preparation and finishing products for over 50 years.

Application Notes

• For machine application — use with a DA (dual-action) or rotary polisher and an appropriate finishing pad; apply with light to medium pressure only
• When used after fine-grade sanding: ensure the surface is clean and dry before polishing; work in overlapping passes until sand scratch haze is fully removed and a uniform gloss is achieved
• When used to remove compound swirl marks: apply after the compounding step while the surface is clean; work in overlapping passes until swirl marks are eliminated
• Prime the pad before starting — apply a small amount of polish to the pad and spread at low speed before increasing to working speed
• Wipe residue with a clean microfiber towel before it dries on the surface
• Inspect the finished surface under adequate lighting — use raking or direct light to check for remaining sand scratches or swirl marks before proceeding to the next step
• After polishing, apply a final ultrafine finishing polish (such as 3M Perfect-It EX, 3M-06069) if required for maximum gloss, then protect with wax, SiO2 sealant, or ceramic coating

Frequently Asked Questions

Q: What is Finesse-It II used for, and how does it differ from a compound or ultrafine polish?
A: Finesse-It II is an intermediate-to-finishing machine polish that sits between a cutting compound and an ultrafine finishing polish in the 3M polishing system. A compound removes heavy oxidation and deep scratches but leaves behind buffer marks and a hazy surface. Finesse-It II removes the compound swirl marks and microfine scratches left by the compounding step — and critically, it is designed for post-sanding use to remove fine sand scratch haze after wet sanding gel coat or paint. An ultrafine finishing polish (such as 3M Perfect-It EX, 06069) then refines the surface to maximum gloss as the final abrasive step.

Q: Is this product specifically designed for post-sanding use?
A: Yes — 3M Finesse-It II is specifically suited for use following fine-grade sanding of gel coat or painted surfaces. Wet sanding removes deep scratches, orange peel, and runs but leaves a fine sand scratch haze on the surface. Finesse-It II removes that haze and restores the surface to a high-gloss, wet-look shine, making it an essential step in gel coat repair and paint correction workflows that involve wet sanding.

Q: Can this be used on marine gel coat as well as automotive paint?
A: Yes — Finesse-It II is appropriate for both marine gel coat and automotive paint (OEM and aftermarket). Gel coat is a polyester-based surface coating used on fiberglass boats and is mechanically similar to automotive clear coat in polishing behavior, making Finesse-It II a directly transferable tool for marine surface repair and finishing.

Q: Does this require heavy pressure to work?
A: No — Finesse-It II requires only light to medium machine pressure. Excessive pressure increases heat generation at the pad, which can cause pad glazing, surface marring, or paint burn-through on thin or aged clear coat. Let the machine speed and abrasive do the work; increase speed before increasing pressure.

Q: Should I follow Finesse-It II with another polish, or is it the final abrasive step?
A: Depends on the desired finish level. Finesse-It II produces a high-gloss, wet-look shine that is suitable as the final abrasive step in many workflows. For maximum showroom-grade gloss, particularly on dark-colored paint where micro-marring is most visible, follow with a dedicated ultrafine finishing polish such as 3M Perfect-It EX (3M-06069) before applying any protective coating.
