RDI is an authorized 3M automotive aftermarket distributor carrying the full lineup of professional collision repair and refinishing products. From Cubitron II precision-shaped abrasives and PPS Series 2.0 spray cup systems to Perfect-It paint finishing compounds and Scotch-Brite surface conditioning products — every SKU is factory-direct from 3M with full manufacturer warranty and guaranteed authenticity. We stock over 500 3M products for body shops, collision centers, dealerships, and independent technicians across the United States.
Every 3M product family for collision repair and automotive refinishing — from raw material removal through final polish.
3M's precision-shaped ceramic grain technology that cuts up to 2x faster and lasts up to 2x longer than conventional abrasives. The triangular grain self-sharpens as it wears, slicing instead of gouging — generating less heat, fewer disc changes per panel, and more cars out the door.
The closed-cup spray system that eliminated gun cleaning in production body shops worldwide. Disposable lid-and-liner system with integrated filtration means zero cup washing, zero cross-contamination, and 60-second color changes. Spray at any angle including fully inverted.
The three-step compound and polish system used in professional body shops and dealership detail centers worldwide. Rubbing compound removes sanding scratches, machine polish removes compound marks, and ultrafine polish delivers show-ready gloss — especially critical on dark colors and tri-stage metallics.
Non-woven synthetic abrasive pads that conform to curved panels and body lines where sandpaper bridges over. The production standard for intercoat scuffing and adhesion promotion in collision repair — Maroon (Very Fine) for primer and intercoats, Gray (Ultra Fine) for pre-clearcoat conditioning.
Disposable atomizing head spray gun system that delivers factory-calibrated HVLP atomization on every job. Instead of cleaning delicate stainless tips after each color, discard the head and start fresh. Consistent finish quality with zero tip maintenance — critical for production environments.
3M 233+ Performance Green Masking Tape is the most trusted automotive masking tape in production body shops globally. Temperature resistance up to 250°F, clean removal without adhesive residue, and consistent conformability across all ambient conditions. Available in every width from 1/8" fine line to 2" panel masking.
We stock the complete 3M automotive aftermarket line, not a curated selection. Every grit, every size, every system — the same depth your 3M rep carries.
As a direct authorized distributor, our pricing comes straight from 3M — no gray market, no middlemen markups, no counterfeit risk.
Orders placed by 2 PM PST ship same day from our Southern California warehouse. Most orders arrive in 2-3 business days nationwide.

What Shops Are Saying
"RDI completely changed how we order supplies. Same-day shipping means we never have to turn away a job because we're waiting on product. The pricing beats our old distributor by a mile."
"Finally a distributor that actually knows the products they sell. Their tech support helped us dial in our spray gun setup and saved us hours of rework. Won't order anywhere else."
"We switched from a big-box supplier to RDI six months ago. Better prices, faster shipping, and the 3M selection is unmatched. Our painters love the Cubitron II discs."
