How to Get a High Gloss Finish Without the Hassle
Achieving a flawless, high gloss finish can be the hallmark of a well-done paint job, restoration, or detail – but anyone in the trade knows it often comes at the cost of time, effort, and frustration. Swirl marks, uneven textures, and dull areas are just a few of the common headaches. But what if we told you that it doesn’t have to be so complicated?
Whether you're working in a body shop, detailing vehicles, or finishing woodwork, this guide shows how to consistently achieve a glass-like gloss using the right combination of products and process – without the hassle.
Step 1: Start with the Right Surface Preparation
The foundation of a high-gloss finish is proper sanding. Uneven or poorly sanded surfaces will always result in poor clarity or dull areas in the top coat.
Use This:
-
Sunmight Gold for aggressive, consistent sanding that doesn’t clog easily.
-
Sunmight Film abrasives for contour sanding and when working on delicate substrates or edges.
-
Sunnet Mesh Discs if dust is your enemy – these discs offer superior extraction and airflow, keeping your work area and finish clean.
Top Tip: Always sand in multiple stages (e.g. 120 → 240 → 400 → 800 grit) for the smoothest base. Jumping grit sizes might seem like a time-saver, but it creates micro-scratches that will haunt you in the final finish.
Step 2: Wash and Decontaminate Thoroughly
Even tiny particles of dust or grease can ruin a perfect finish. A premium wash and wax shampoo not only cleans, but also helps protect during the prep stage.
Best Choice:
-
Ultra Violet Premium Wash & Wax – a pH-balanced, high-foaming shampoo that leaves a wax-infused protective layer. Perfect for prepping before paint correction or coating application.
-
Blue Blazes Concentrated Wash & Wax – offers powerful suds and excellent rinse-off, ideal for fleet or high-volume work.
-
Presta Fast Wax – great as a final wipe-down after wash for that pre-buff gloss boost.
Don’t Skip: Degrease surfaces properly before any coating or polishing. Use a dedicated degreaser to remove any residues from waxes or polishes.
Step 3: Polishing Like a Pro
Now that your surface is clean and smooth, it’s time to bring out the gloss. A good compound or polish will remove micro-scratches, enhance clarity, and increase reflectivity.
Pair With:
-
Sunmight Finishing Discs or Foam Pads – engineered for use with polishing compounds, offering a smooth cut and refined swirl removal.
-
Machine Polishers (DA or Rotary) – if you’re serious about gloss, hand polishing won’t cut it. Use a quality machine for consistent pressure and heat distribution.
Product Highlight:
While Sunmight focuses primarily on abrasives, many body shops pair their finishing discs with trusted compounds from brands like 3M, Menzerna, or Gyeon for stunning results.
Step 4: Lock in the Shine
A glossy finish looks great – but it won’t stay that way without proper protection. The last step is sealing in your work.
Protect with:
-
Presta Fast Wax – ideal for a fast, glossy topcoat that enhances the finish without the greasy feel.
-
Ultra Violet Wash & Wax doubles up here again, ideal for maintenance washes post-detail to preserve gloss and water repellency.
