SPB Magic Juice 4oz Polishing Compound for Resin Blanks

The Magic Juice polishing system

SPB Magic Juice is the six-step numbered polishing compound system designed specifically for pen turners working with solid resin blanks, embedded-object casts, plastics, and CA or Craft Coat finishes. Each bottle represents a progressive grit that builds gloss from coarse cut to mirror shine on the lathe. The new numbered labels make the workflow easier to follow while the trusted water-based formula remains unchanged. This 4oz jumbo set gives high-volume turners or production shops enough compound to complete dozens of barrels without frequent reordering. Pen turners choose Magic Juice because it delivers consistent professional results on resin pen blanks where ordinary compounds fall short, turning a good finish into a true showpiece.

Progressive polishing matters because each step removes the micro-scratches left by the previous grade. Skipping steps or using the wrong order leaves swirl marks that ruin the final gloss. The system works exclusively on sealed surfaces, making it the go-to lathe polish once your resin or hybrid blank has been properly prepared.

What's in This Set

The 4oz jumbo set contains the complete six-bottle system (STEP #1 through STEP #6) in larger 4oz bottles. It is ideal for everyday production turning, teaching workshops, or any shop that finishes multiple resin or hybrid projects each week. Unlike smaller sample or 1oz sets, this size reduces refill frequency while still allowing precise control over each progressive step. High-volume turners appreciate the economy and the peace of mind that comes from having every grade on hand in generous quantities.

How to Polish with Magic Juice

Follow this proven lathe workflow for consistent high-gloss results on resin and sealed blanks.

• Prep: Wet-sand to 800–2000 grit (2000 preferred) before applying any compound.

• Lathe speed: Run the lathe between 2400–3000 RPM for optimal heat and cutting action.

• STEP #1–#6: Apply a pencil-eraser-sized dab from each bottle in numerical order. Use mild pressure for 20–60 seconds per step. Advance to the next bottle only when the surface feels noticeably smoother.

• Sealing: Porous or hybrid wood blanks must first be sealed with CA or Craft Coat before polishing with Magic Juice.

• Not for: Raw unfinished wood or friction-polish finishes.

• Storage: Magic Juice is water-based; do not allow the bottles to freeze.

Trusted by pen turners since the original formula launch, this water-based, non-freeze protected system delivers reliable results on the lathe every time. The larger 4oz bottles keep your workflow moving smoothly through multiple projects.
