01
Confirm the correction
Deep scratches, oxidation, and visible prep marks should be resolved before this stage. Finishing compound will not replace sanding or cutting.
Description
Professional finishing compounds
Refine the final pass. Reveal the mirror.
Competition Purple and Blueberry are low-cut, fine-abrasive compounds designed to maximize clarity and luster after preparation, cutting, and coloring are complete.

How the final stage works
A mirror finish is refined, not forced.
Finishing compounds remove faint haze and improve optical clarity with minimal cutting action. They work best only after the previous stages have produced a uniform, defect-free foundation.
02
Use a clean fine wheel
Pair the selected bar with a dedicated UBM or flannel finishing wheel so heavier abrasive from prior stages cannot contaminate the finish.
03
Inspect the reflection
Use clean lighting and stop when clarity improves. Repeated passes cannot repair defects that belong to an earlier stage.
Final-stage compound and a soft finishing wheel refine the work created by the cutting and coloring stages.
Compare the two formulas
Balanced final refinement or ultra-fine clarity.
Both formulas work across broad humidity and temperature ranges. Choose Competition Purple for a dependable final-stage balance or Blueberry for the least cut and finest abrasive profile.
Competition Purple
Fine abrasive grains and a balanced consistency that is neither especially wet nor dry.

Which bar should I choose?
Use the remaining haze and finish target as your guide.
Choose Competition Purple when...
- You want slightly more corrective ability at 2/10 cut.
- You prefer a balanced, medium-dry working character.
- You need a versatile final-stage bar across changing shop conditions.
- You are following a coloring compound with a flannel or UBM wheel.
Choose Blueberry when...
- The surface is already highly refined and needs minimal cutting.
- You want a very dry, ultra-fine finishing bar.
- Your priority is optical clarity and final luster.
- You are removing only faint finishing haze rather than deeper defects.
Surface preparation
The final pass can only refine what is already there.
Before finishing, the surface should be clean, uniformly polished, and free of deep preparation marks. Correct visible defects in the stage that created them.
Every project is different. Metal type, surface condition, prior abrasives, existing finish, damage level, and desired result determine the preparation and earlier polishing stages required.
Contamination matters: use a dedicated wheel for each compound and keep finishing wheels away from cutting dust and coarse abrasive residue.

Application process
Keep the load light and the finishing wheel clean.
Mount safely
Install the clean UBM or flannel finishing wheel with proper safety flanges. Confirm the machine and wheel speed ratings before use.
Rake the edge
Prime a new wheel and remove hardened buildup from a used wheel. Never carry coarse compound into the finishing stage.
Apply sparingly
Touch the bar lightly to the spinning wheel. Too much compound can smear, load the wheel, and reduce clarity.
Move and inspect
Keep the wheel moving, monitor heat, and inspect frequently. A common finishing range is 1,800–2,200 RPM, always within equipment ratings.
Expected result
Final clarity across polished metal applications.
Use finishing compound on properly prepared aluminum and stainless surfaces including wheels, tanks, and trim. Test the complete process in an inconspicuous area first.
Machine-polishing safety
Protect yourself before the wheel starts spinning.

Frequently asked questions
Finish with control and confidence.
What is the difference between Competition Purple and Blueberry?
Competition Purple has a 2/10 cut and balanced 5/10 dryness. Blueberry has the least cut at 1/10, a 6/10 dryness rating, and super-fine abrasive grains for maximum refinement.
Can finishing compound remove scratches?
It can refine only very faint haze or micro-marring. Deep scratches, oxidation, and visible sanding marks require the appropriate preparation, cutting, or coloring stage first.
Which buffing wheel should I use?
Use a clean, dedicated soft finishing wheel such as a flannel or UBM wheel that is appropriate for your machine, metal, and target finish.
Can I use the same wheel from the coloring stage?
No. Residual abrasive from a prior stage can reintroduce haze. Keep each compound on its own clearly identified wheel.
How much compound should I apply?
Use a light, brief application to the working edge. Reapply only when polishing action falls off, and rake the wheel if buildup develops.
What speed should I use?
A common final-stage range is approximately 1,800–2,200 RPM. Always follow the lowest rated speed of the wheel, flanges, adapter, and machine, and adjust technique to the project.

"Excellent product"
Trying new products
"I’m an owner operator that polishes my own equipment, for the last several years i have been using a “competitors” brand cutting compound and buffing wheels. Decided to give renegade a shot this year and am extremely glad i did! Hands down the best polish on the market the other products i was using don’t remotely compare. Looking forward to trying more of their stuff on my truck!"
"Renegade products is all i use in my shop and all i will continue to use in my shop!! Keep the product line coming!!!"
Awesome products
"Their compounds and wheels are far superior to any others i polish on the side and have always gotten awesome results using their products"
Shipping takes forever per usual
"I got the express shipping and still took way too long"
"I’ve been experimenting with this and the competition purple for my finishing, and I like that I can run this at a little higher RPM without burning the color into the metal unlike the purple bar you have to keep it at a low rpm"
