Professional-Grade Pressurized Spray Gun for Marine Coatings
The 3M Accuspray™ HGP20 is a pressurized spray gun kit engineered for high-productivity coating applications on boats, hulls, and marine surfaces. Its standout feature is the replaceable atomizing head — instead of cleaning or rebuilding a worn gun, you simply swap the head and get like-new atomization performance every time. This dramatically reduces downtime and coating waste, making it a smart choice for anyone applying topcoats, primers, or antifouling paints.
What's Included
- 1 × HGP20 pressurized spray gun body
- 3 × replaceable atomizing heads
Note: Cup and hose are sold separately.
Best Use Cases
- Applying marine topcoats, primers, and antifouling paints to hulls and topsides
- High-volume production painting where consistent atomization and finish quality are critical
- Situations where fast head swaps between coats or colors save significant time
- Professionals and serious DIYers who want spray gun performance without the cost of a full replacement unit
Parts Desk Insights
The HGP20 is a pressurized (HVLP-compatible) gun, meaning it requires a pressurized cup or remote pressure pot — the gun body alone won't operate without one. If you're setting up a complete system, pair it with compatible atomizing head refill kits to maximize the value of this kit. The three included heads give you a solid starting inventory for a full paint job, but having extras on hand is recommended for multi-coat or multi-color work.
