The 3M rubbing compound 3-stage system is a must for paint shops who finish products by hand. Suitable for use on any surface, it's an easy-to-use system that is fast and produces a professional finish. And if you're a DIY polisher, it's an affordable way to achieve professional results, with the full kit coming in at around £500.
What makes the 3M rubbing compound system so easy to use?
Global giant 3M has demonstrated that it knows its stuff when it comes to simplifying the compounding and polishing. Their 3-step system colour codes each step to make sure that you use the right kit at every stage of the process.
For each phase of finishing, you have a specific colour pad, compound/polish bottle cap, and cloth.
Why?
- To make the process easy to follow
- To prevent contamination between the different compounds and polishes
- To prevent you from using the wrong grade of cloth at the final stages
The system
Use 3M compounds with the lightweight and powerful 3M electric polisher, which is suitable for both vertical and horizontal panels.
STAGE 1 - Green (fast cut)
This first stage removes fine abrasive scratches from the spray booth/paint rectification process.
Step 1: Attach the GREEN compounding pad to the polisher.
Step 2: Apply 3M Fast Cut Compound (GREEN cap) to the pad and spread it evenly.
Step 3: Before switching the polisher on, hold the pad against the panel to prevent compound slip. Polish the panel.
Step 4: Wipe off any excess residue with the GREEN high-performance cloth.
STAGE 2 - Yellow (fine cut)
This stage uses an extra fine polishing compound to further refine the finish.
Step 1: Replace the green pad with the YELLOW pad.
Step 2: Follow the same process as for Stage 1, but using 3M Extra Fine Compound (YELLOW cap) and the YELLOW cloth.
If you're polishing a light colour panel, stages 1 and 2 may be enough to give a high-gloss, end finish. However, your surface may have developed holograms and swell marks, especially if you're working on dark coloured panels. Follow Stage 3 to remove these.
STAGE 3 - Blue (final polish)
Step 1: Swap the yellow pad for the BLUE pad.
Step 2: Apply the 3M Ultrifina SE Polish (BLUE cap) to the pad. Unlike other compounds and polishers, this product remains in a liquid state.
Step 3: Wipe away excess residue with the ultra-soft BLUE cloth. Using the yellow or green cloths may introduce scratches at the final stage.
Step 4: Time for a final inspection. Ensure to check that all denibs have been sorted for a premium finish.
