Question 1

How much does Tesla Rust Check cost in Bowmanville?

Accepted Answer

Model 3: $140 to $160 by configuration. Model Y: $160. Model S: $140 to $150. Model X: $160 to $170. Coat & Protect oil-based undercoat is included on every tier. One-time $10 first-drill charge if access holes need to be added. Pricing matches comparable size combustion vehicles.

Question 2

Does my Tesla actually need Rust Check if it has aluminum body panels?

Accepted Answer

Yes. Aluminum body panels do not corrode the way steel does, but the structural elements of every Tesla are still steel or steel-aluminum composite: floor pan reinforcements, subframe components, suspension mounts, brake lines, and the battery pack enclosure framework. Ontario road salt corrodes that steel exactly the way it corrodes any other vehicle. Annual Rust Check protects the steel underbody.

Question 3

Will Rust Check damage my Tesla battery pack?

Accepted Answer

No, because we do not spray Coat & Protect directly onto the battery pack enclosure. Step 2 application is modified for Tesla: we coat the underbody steel structure around the battery (subframe, suspension components, brake lines) but the battery pack itself is masked off. The battery enclosure has its own factory corrosion-resistant coating, and we do not introduce a foreign product onto that surface.

Question 4

Is Rust Check compatible with EV systems?

Accepted Answer

Yes. The Rust Check oil formula does not contact electrical systems, motor windings, or battery internals. Application is to body cavities and underbody steel structure, both of which are functionally identical to combustion vehicles. We do modify Step 2 around the battery pack enclosure as a conservative choice. Other than that, the process is the same as on any other vehicle.

Question 5

Will Rust Check void my Tesla warranty?

Accepted Answer

No. Rust Check is approved by all major manufacturers including Tesla and does not void any factory warranty in Canada. Tesla service centres do not currently offer rust protection as part of their service menu, so independent licensed Rust Check dealers are the primary path for Tesla owners who want annual corrosion protection.

Question 6

When should I book my Tesla for Rust Check?

Accepted Answer

October through November is the high-leverage window before the first salt application. Tesla owners who use their vehicles 12 months a year through Durham Region winters benefit most from consistent annual treatment because the underbody salt-spray exposure is identical to combustion vehicles regardless of how the propulsion works.
