Stop-Leak Products: Improve Sales and Customer Satisfaction Through Upselling

Convincing a customer to spend a few more dollars for a premium chemical stop-leak product can be a tough sell. But the benefits – for customers and your store – are worth it.

Convincing a customer to spend a few more dollars for a premium chemical stop-leak product can be a tough sell. But the benefits – for customers and your store – are worth it. 

Choosing premium products can save customers money and effort over time because their repairs last longer and the products protect the vehicle against future breakdowns. At the same time, these premium sales boost your store’s bottom line.

So how do you successfully move a customer from an entry-level product to a premium solution?


Start by educating yourself on the options. Often there are several chemical solutions to a vehicle problem, and your customers count on you to help them determine which one is best. For example, Bar’s Leaks alone offers eight different cooling system stop-leak products. Study the product packaging, visit the manufacturers’ websites – call the company if you have to – until you understand the differences between products.

“We spend a lot of time making sure our packaging showcases the benefits of our premium products,” says Tim Byrnes, director of sales for Holly, Michigan-based Bar’s Leaks. “This helps narrow the knowledge gap for countermen and allows them to get to know the product enough to recommend it. It also helps customers see the differences for themselves. Our website is also a great resource for countermen to quickly access product information using a computer or mobile device. The interactive ‘Three-Minute Mechanic’ feature on the site will even walk them through diagnosing vehicle issues and recommending the best solution.”


Ask your customer what the problem is and listen carefully to the answer. Does the customer know exactly what’s leaking? Does it sound like a simple leak that an entry-level product would fix? If so, recommend an appropriate product. Otherwise, ask some follow-up questions. What color is the liquid? Where is the customer finding it? How often? How much? When did this leak start? How old is the vehicle? Are there other issues with the vehicle, like overheating? If it sounds like the vehicle has multiple problems, then a premium product that addresses multiple issues and protects against future damage is in order. And don’t feel bad for asking a lot of questions – this tactic helps build customers’ trust in in you.

“Some customers might not even know what kind of fluid is leaking,” says Byrnes. “In these cases, it might be best to recommend a premium product that can help with multiple issues or applications. If that’s the case, customers may be more willing to choose the premium product.”


Based on your understanding of the problem and the potential chemical solutions, recommend the product that you think will work best. Remember that you’re the expert, so make this recommendation personal (“I recommend,” not “the bottle says”). Explain why you’re recommending a more expensive product ­– demonstrate the value of that product. The word “because” is very helpful here. For example: “I recommend Bar’s Leaks Liquid Copper for your car because you can simply pour it in and it will permanently fix your large leak – you don’t need to worry about draining the cooling system first.”

Point out how choosing the premium product can save the customer money. For example, “This product creates a permanent seal that’s even stronger than the original, so you won’t ever have to buy another bottle of radiator stop leak.” Highlight any available rebates that can make a premium product even more affordable.

You want customers to trust you, so don’t upsell when a regular product will work fine. A satisfied, repeat customer always should be the goal.

“Our products have the highest success rate when countermen don’t upsell just for the sake of upselling,” says Byrnes. “Some situations only warrant a more basic product that will still keep customers on the road and save them from costly repair bills.”
