Users highlight notable improvements in surface gloss, reporting success on projects ranging from bathtubs to resin art. The kit is praised for its easy application—just sand, buff, clean, and polish for renewed clarity.
However, customer feedback is mixed regarding cost and performance, with some finding the results excellent while others feel it underperforms compared to price expectations.

How to Choose the Perfect Polishing Compound for Epoxy Resin
A comprehensive guide based on real-world testing and user feedback
What Actually Matters When Shopping
1. Abrasive Type & Grit Fineness
The right abrasive ensures you restore gloss without scratching the resin further. Too coarse and you may damage delicate finishes; too fine and you may not remove existing blemishes.
Look for
Look for diamond, aluminum oxide, or cerium oxide compounds with a 'fine' or 'ultra-fine' designation for general repairs. Use a heavier cut for deep defects.
Avoid
Avoid compounds labeled only for 'automotive paint' without resin compatibility or those with unknown abrasive ingredients.
2. Compatibility & Intended Use
Not all polishes designed for cars or metal work well on epoxy resin. Some may contain fillers or oils that harm resin clarity or cure.
Look for
Check the label for 'resin safe' or 'epoxy compatible'. Kits dedicated to epoxy are safest bets for home and art projects.
Avoid
Watch out for high-silicone or oil-heavy polishes, which can cause haze or residue on cured resin.
3. Kit Completeness & Accessories
Buying a full kit saves the hassle of sourcing extra tools. Cleaner and buffing accessories can noticeably impact your results.
Look for
Kits that come with polish, cleaning compounds, pads, and microfiber towels provide the best value.
Avoid
Barebones bottles with no instructions or required tools may lead to frustration and inconsistent shine.
Your Decision Framework
Choosing the right polishing compound starts with honestly assessing your project's needs and your comfort level with finishing tools.
Evaluate the Severity of Your Surface Defects
Match the compound's cut strength to your scratch severity.
- • Are you fixing light swirls, or deep gouges?
- • How much material are you comfortable removing?
- • Will you need a follow-up fine polish for gloss?
Decide on DIY vs. Professional Finish
Determine how precise or repeatable your results need to be.
- • Is this a showpiece, gift, or daily-use item?
- • Do you have access to buffing machines, or only hand tools?
- • Are you polishing epoxy only, or also glass/metal inlays?
Assess Kit Value and Usability
Save time and money by choosing kits that match your workflow.
- • Will a kit with cleaning agents and accessories speed up your process?
- • Are the instructions clear for your skill level?
- • Does the brand offer good support/documentation?
Avoid These Common Mistakes
1. Choosing Based Solely on Price
• Why problematic: Cheapest options may lack fine abrasives or leave residue, leading to more work or even ruining your piece.
• Better approach: Select products rated for epoxy by experienced users, and compare kit inclusions—not just price.
2. Using Car or Metal Compounds Unlabeled for Resin
• Why problematic: Unlisted ingredients can react with the resin, causing clouding or soft spots.
• Better approach: Stick with resin-dedicated or clearly multi-use (resin safe) polishes.
3. Skipping Grit Steps Before Polishing
• Why problematic: Polishing without properly sanding first will not remove deep marks and can waste both time and product.
• Better approach: Always sand through recommended grits before moving to compound—especially after casting resin.
Budget vs Reality: What You Actually Get
Under $30
Reality: Entry-level resin-only kits with basic tools. Great for touch-ups, small craft projects, and routine shine restoration.
Trade-offs: May not handle deep scratches; limited in size and abrasiveness.
Sweet spot: Best for beginners or periodic hobbyist use.
$30-$45
Reality: Well-rounded kits with higher-quality abrasives, often including cleaning agents or multi-step formulas.
Trade-offs: Still kit-size (not bulk); may require machine buffers for pro-level results.
Sweet spot: Ideal for serious DIYers and those finishing larger or more visible resin pieces.
Over $45
Reality: Premium compounds and comprehensive kits with multi-surface compatibility, extra accessories, and professional grit.
Trade-offs: Costlier—worth it only for frequent users or those demanding flawless, mirrored finishes.
Sweet spot: Go premium if you work resin commercially or require the finest gloss for trophies or installations.
Pro Tips for Success
1. Before You Buy
Check that the compound is specifically labeled for epoxy resin or is widely reviewed by experienced resin artists.
2. First Week of Use
Test on a small, non-visible section of your work to ensure the grit and formula produce the finish you want.
3. Long-term Care
Regular light polishing can prolong the high-gloss finish; store compounds airtight, away from humidity.
4. When to Upgrade
If a compound is leaving haze or not removing scratches, move up to a heavier cut—or invest in a multi-step kit.
