Yes — 100%. RDI is an authorized distributor for every brand we carry, including 3M, Sunmight, Evercoat, SATA, and SEM Products. All products are sourced directly through official manufacturer channels, factory-sealed, and backed by full manufacturer warranties. We do not sell gray-market, expired, or counterfeit products.

We carry the top professional brands in automotive refinish: 3M (abrasives, compounds, tapes, masking systems), Sunmight (sanding discs and rolls), Evercoat (body fillers, putties, glazing compounds), SATA (spray guns and accessories), and SEM Products (adhesives, sealers, trim coatings). Our catalog is constantly expanding based on customer demand.

Our focus is on the supplies that surround the paint process — abrasives, body repair, masking, spray equipment, and finishing products. For basecoat, clearcoat, and primer-surfacer, we recommend working with your local paint jobber who can provide color matching services. We do carry some SEM aerosol coatings and Evercoat primer products.

Some chemical products like body fillers, glazing compounds, and adhesives do have shelf lives, typically printed on the packaging. We maintain high inventory turnover to ensure you receive the freshest product possible. Abrasive products (sanding discs, rolls, sheets) do not expire when stored in a cool, dry environment.

Absolutely. If you cannot find a specific product on our website, contact us with the manufacturer part number, product name, or a description of what you need. If we carry it, we will send you a direct link. If we do not carry it yet, we will look into adding it to our catalog or suggest an equivalent alternative.

Yes. We offer tiered volume pricing for collision centers, dealerships, carwashes, and wholesale accounts. Discounts increase with order volume. Contact our sales team to set up a commercial account with pricing customized to your purchasing volume and product needs.

Qualified commercial accounts can apply for net-30 payment terms. This is available to established businesses with a verifiable credit history. Contact our sales team to discuss eligibility and submit a credit application. Approval typically takes 1–2 business days.

If you find a lower price on an identical, in-stock product from another authorized distributor, send us the quote or screenshot and we will match it. This applies to current, published prices from authorized resellers — not auction sites, closeout liquidations, or unauthorized sellers. Contact us with the details and we will respond within one business day.

Yes. If your business qualifies for sales tax exemption, submit your tax exemption certificate or resale certificate to our team. Once verified and on file, all future orders will automatically be tax-exempt. This process typically takes 1 business day.

It depends on the repair stage. For a quick reference: 80 grit for stripping and filler shaping, 150–220 for filler finishing and featheredging, 320–400 for primer leveling, 500 for pre-paint prep, and 1000–3000 for clearcoat color sanding. For a complete breakdown, check our Sandpaper Grit Guide which covers every repair scenario in detail.

PSA (Pressure Sensitive Adhesive) discs stick directly to the sander pad like a sticker — they cut aggressively and cannot be repositioned. Hook & Loop discs attach via a velcro-style system, making them easy to swap between grits. PSA is best for heavy removal work (36–180 grit), while Hook & Loop is preferred for multi-step sanding sequences (120–600 grit). See our Grit Guide for a full comparison.
