Welcome To Bay State Rust Prevention & Undercoating

Fleet Undercoating and Rust Protection for Commercial Vehicles

Massachusetts road salt is hardest on the vehicles that are out every day. Bay State Rust Prevention & Undercoating protects work trucks, vans and company vehicles at our shop in West Boylston, serving businesses across Worcester County.

What We Do for Fleets

WaxOyl Undercoating

Full-vehicle WaxOyl rust prevention for newer and rust-free vehicles. It gets into seams, frame rails and cavities and stays flexible, so it keeps protecting through the winter. Starts at $799 per vehicle.

Rust Removal & Sandblasting

For work trucks that already carry years of salt damage. We sandblast affected surfaces down to bare metal and rebuild the protection, instead of coating over rust. Starts at $1,000.

Frame Repair

For trucks and SUVs that failed inspection because rust has eaten through the frame. We cut out the damaged section and weld in a replacement. Guaranteed to pass Massachusetts state inspection (the guarantee covers passing inspection, not parts or labor). Starts at $500.

How a Fleet Quote Works

Send us your company name, how many vehicles you have, their makes, models and years, and when they can be off the road. You can use the contact form or call (508) 859-9714.

Every job starts with a no-charge inspection, so each vehicle gets the treatment it actually needs: prevention for the newer ones, rust removal or frame repair for the ones that need it. You get a straight quote before any work begins.

The best time to undercoat is late summer to early fall, before the roads are salted, but we apply WaxOyl year-round. A truck treated mid-winter is still far better protected than one left untreated.

Our shop is at 156 Hartwell St, West Boylston, MA 01583, open Monday, Tuesday, Thursday and Friday 8:00 AM to 6:00 PM and Wednesday 8:00 AM to 6:30 PM.
