How Pricing Works
QUOTE PER PROJECT
Powder Coating & Surface Prep
Every powder coating project varies by size, complexity, color, and prep requirements. We don’t publish flat pricing because a ballpark number often misleads. Request a quote and we’ll give you an accurate number for your specific job.

Retinning and whip rewiring are priced by standardized equipment size and type. Full pricing tables are published on each service page – no need to call for a quote on most common items.
Common Questions
Frequently Asked Questions
It depends on what your equipment is made of and what you’re trying to accomplish. If you have food-contact equipment made of carbon steel or cast iron, retinning is likely what you need. If you have metal parts that need a durable protective or decorative finish, powder coating is the right fit. If you have a commercial mixer whip with broken wires, that’s whip rewiring. Not sure? Give us a call – we’re happy to help you figure out the right approach before you ship anything.
No minimum order is required for retinning or whip rewiring – we handle individual items as well as large commercial orders. For powder coating, project size and complexity factor into pricing, so it’s worth calling ahead on very small jobs to confirm it makes sense.
Yes. Our pickup and drop-off hours are Monday–Friday, 7 AM–3 PM at 1700 Elida Road, Lima, Ohio 45805. For large or complex orders, we recommend calling ahead so we can be prepared for your arrival.
Yes. If you’re outside the Lima, Ohio area, you can ship your equipment directly to us. Please include a packing list with your name, return address, contact information, and a description of each item so we can process your order accurately.
For retinning and whip rewiring, yes – the listed prices include all standard processing (blasting, prep, and coating for retinning; wire replacement for whip rewiring). Powder coating is quoted per project and will include any prep work required. Prices are F.O.B. our dock in Lima, Ohio; shipping costs are the customer’s responsibility.
We’ve been in operation since 1936 – nearly 90 years. For retinning specifically, that depth of experience matters because we are one of the few companies in the United States still offering this service. Most competitors have stopped. Our longevity means we’ve seen virtually every type of food equipment that needs reconditioning, and we know how to handle it correctly.
